The Open Symbol Project aims to create an open collection of schematic symbols and PCB footprints released under a license that does not interfere with use in either commercial or free projects. Work is currently empahasising PCB footprints, particularly for surface mount parts. Land size calculations are based on the &IPC-7351-draft;,the successor to IPC-SM-782, with component dimensions largely taken from JEDEC standards. These calculations take into consideration the sizes of the parts. Work is empahsizing the footprints, in part, because I have not had a chance to write a GUI application that will allow entry of schematic symbols with all the extra information I want to include (including pin swapping, etc.) Footprints are being primarly generated by programs written in C. A software library has been created which currently has output drivers for Xpcb, eagle, DXF, and Circad. The primary program is designed for square and rectangular QFP packages but SOIC, SOP, most SOTs, and even chip resistors and capacitors are handled as degenerate forms of a QFP. Because the footprints are generated from calculations rather than a fixed pattern, they can easily be modified to accomodate various design rules. This site and the project are in the early stages of constrution, but I wanted to get something up so the search engines will index it. I am currently busy doing the first micro board designed using these symbols and the software to drive it. This diagram shows the flow through various parts of the system for PCB footprints. Portions which don't exist yet are shown with dotted lines. This diagram is availible in PNG, PDF, Encapsulated Postrict, and Open Office Draw formats. [PCB Footprint Flow Diagram] PCB Footrpint overview diagram This next figure shows some sample footprints including rectangular quad flat packs (easier to screw up than the square kind), SOIC/SOP/TSSOP, chip resistors, chip capacitors, chip diodes, right angle D-sub connector, 2.54mm shrouded headers, and flat flex connectors They are shown here at enlarged 2:1 (on 100dpi screens). The lead pitch is so fine that you will see considerable aliasing artifacts which is why the pin spacing seems irregular. Even on a laser printer, there are noticable artifacts. At 300dpi, the lead pitch is only 3.5 pixels wide. At 600dpi, there are still noticable artifacts. This figure is also availible in xpcb, PNG, PDF, and Postscript formats.

The standard file format is still under development. I expect to include the following features: Text based. Probably XML based. Able to define symbols with variable numbers of pins. Include optional simulation data. Verilog, VHDL, and Spice. Gate swapping, pin swapping, and complex pin swapping with linked input and output pins that can be swapped together. Multiple gate types within package. Symbol. Better handling of text rotation and alignment. Does text right itself after being rotated 180 degrees or do true rotation? If it is attached to a pin that is rotated 180 degrees, does it climb on top of the pin or stay underneath? Are text alignment points based on the text baselines or the postions of the lines they are labeling? (With gschem, you can't snap text to a 100 mil grid and have it line up properly with lines on a 100 mil grid. All of these alignments will be specifiable. May have ECMAscript based scripting. Javascript is a terribly insecure thing when included in web browsers but that is because of the STUPID browser API bindings. The core language is weak enough that you can't do anything more dangerous than waste cpu cycles. Key parameters. The format will include provisions for specifying key parameters (zener voltage, resistance in ohms, gain, wattage). Technology information: through hole, surface mount, reflow compatible, etc. Optional 3D modeling information. At the very least, a part height is desired so silk screen outlines can be extruded upwards.

I am working on machine generated symbols for 74XX logic. To that end, I have created a program that has abstract definitions of parts from 74XX00 to 74XX99 but I haven't had the program generate the symbols yet. For gates, the program will draw the gates. For block symbol parts, the data contains enough information to place pins in appropriate locations, handle pin swapping, etc.

The license will definitely not be any form of GPL. The license will be more in the true spirit of Public Domain and Creative Commons. I haven't worked out the exact terms of the license. Credit where credit is due. But there won't be any requirement to include credit in print advertising. Credit somewhere on the website would be appropriate. No blame where it isn't due. I.E. if you change it you must indicate that it has been modified. No warranty or liability. There will be a prohibition on redistributing libraries relicensed under GPL but I would like to find a way that users can mix symbols with GPL symbols if they use a program whose default libraries contain such an objectionable license. If you have ideas on how to do this, let me know.

To produce commerical designs. To produce free designs distributed under Public domain, BSD, MIT, creative commons, and other reasonable licenses. To produce designs which are copyrighted and can be licensed for a fee but full schematics, pcb layouts, etc. are availible for download. To distribute with CAD packages. Vendors will be encouraged to keep the library separate from their proprietary license and to donate some of their own symbols. Distribution of symbols by component manufacturers and distributors via websites, cd-rom, etc. for parts they sell.

I could use some help entering data from the JEDEC standards for the qfp program. See spreadsheet format below. My time would be better spent on creating the utilties, file formats, and documentation for this project. Send me any schematic symbols and pcb footprints you are willing to donate. They can be created using any schematic capture or pcb layout package as long as it has an ASCII file format (some which use binary formats such as eagle and protel can export as ascii). Please include a URL for the file format specfication. I will write a converter. Even if these symbols/footprints do not meet the standards of this project, they may be helpful to others as is or reduce the amount of data we need to enter to produce high quality symbols. Even symbols that don't meet the graphical standards and have pin swap information still have pinnumber/pinlabel information that can be extracted. If you have donated symbols to gEDA or xpcb, you can still donate them to this project if you did not create them by modifying existing GPLed symbols or other symbols with incompatible licenses. This command will update the license attributes on all symbol files in the current directory. perl -p -i -n -e "s/license=GPL/license=Open Symbol License/" *.sym I need documentation on the file formats used by various commercial CAD packages. Donations: Copies of IPC standards or the money to buy them. sample parts that can be used to check footprints.

The use of a spreadsheet to enter data from the standards is a bit of a kludge but it turns out to be a fairly efficient way to define lots of similar parts. I am thinking of providing a web interface in the future that will work with standards that define only a few parts or many parts. All the data from a typical standard can be entered in one evening. Basically, all dimensions are entered into a spreadsheet. Any spreadsheet can be used: gnumeric, oocalc, Excel, Lotus 123, etc. For data entry convenience, spreadsheat columns are entered in the order the data is listed in the standards documents. The data is then saved in CSV (comma separated ASCII) format. Typically, the standard will have data in three sections. First will be a list of all components, with a few key parameters. This data is entered into the first columns. Second, there will be a list of data common to all parts or all parts with a given lead pitch. Those are entered once and then copied and pasted into the last columns after the individual part data is entered. Third, there is data specified for each part variation. This is entered in the middle columns. Be careful, the parts are frequently listed in a different order in this section. Then, additional columns of data are added: In the first column, enter the IPC-7351 naming convention prefix for this class of part ("PQFP", "SOP", "SOIC", etc.) In the second column, enter the IPC-7251 pintype as used by the qfp program. #define LEAD_TYPE_GULL_WING 0 // gull wing, pitch >0.625 #define LEAD_TYPE_GULL_WING_SHRINK 1 // gull wing, pitch < 0.625 #define LEAD_TYPE_J_LEAD 2 // J leads #define LEAD_TYPE_RECTANGLE_END 3 // rectangle or square-end components (caps and resistors) #define LEAD_TYPE_MELF 4 // Cylindrical end cap terminations (MELF) #define LEAD_TYPE_BOTTOM_ONLY 5 // Bottom only terminations #define LEAD_TYPE_LEADLESS_CASTELLATED 6 // Leadless chip carrier with castellated terminations #define LEAD_TYPE_BUTT_JOINT 7 // butt joints #define LEAD_TYPE_INWARD_L 8 // Inward flat ribbon L and gull-wing leads (tantalum capacitors) #define LEAD_TYPE_LUG 9 // Flat lug leads #define LEAD_TYPE_FLAT_NO_LEAD 10 // Flat, no lead #define LEAD_TYPE_SO_NO_LEAD 11 // Small Outline (SO), No-lead SON? Pin counts. Add 4 columns with the pin counts on the top, bottom, left, and right sides of the part. Frequently, a formula can be used to derive this from the total pin count but for rectangular QFPs you need to enter this manually. The source document. I.E. "MS-026" The name of person entering (or last updating) the values. Any required program variables which are not specified explicitly in the standard but which can be calculated from it. Data starts on row 3. The first two rows have special meaning. In the second row, enter the names of the variables as they appear in the standards document. In the first row, enter the variable names for the qfp program. Data is to be entered in mm. If the standard only specfies inches, convert by using the spreadsheet to multiply by 25.4. Comments are entered in column 1 starting with a "#" character, below the data rows. Include the URL of the source document as a comment. Include any assumptions that were made. Include your email address in a comment if you don't mind your email on the web. Include a comment that describes the packages covered by this file. Include a comment if you haven't entered all parts defined by the source document or if you didn't do adequate error checking. # Correction: corrected a typo in the source document for part AA, E=0.65. # Assumption: lead count per side for 14x20 package not specified, assumed base on other rectangular 128 pin packages. # SourceURL: MS-999 http://www.jedec.org/download/search/MS-999.pdf # Contents: This file describes 0.150 mil body width, 50 mil lead pitch SOIC # Contributor: Mark Whitis <whitis@freelabs.com> http://www.freelabs.com/~whitis/ Include all dimensions specified in the standard. Even if they aren't required to generate a footprint they may be required to generate a 3D model. Where variables, for L for example, are specified as min, nom, max, label the columns Lmin, Lnom, Lmax. You will notice that some cells are empty for all variations, for example they may specify min and max but not nom for all variations. In that case, you do not need to include a column for Lnom. Fortunately, they are usually consistent within a particular document about which values they omit which simplifies data entry since you can just type all the numbers printed separated by tabs and not need to look at the computer until you get to the end of the line. In order to insure accuracy, all data is entered twice. The second copy is in a block of rows below the block containing the additional data. They are separated by "#end" in column 1. The common data must be reentered again and can then be cut and pasted to each row but don't copy and paste it from the top block of data. A third block of rows is created with one cell for each cell in the preceeding two blocks. This contains a formula used to test for equality. In gnumeric, for example, use =A1=A100 to compare cells A1 and A100. Not that if you move cells of data, you may need to recopy the equality formalas since their references may also move. This process is tedious but it eliminates many errors and is needed to prevent errors.. Leave the second copy of the data and the comparison as an indication of data accuracy. Include only data which may be legally incorporated. Tables of facts can usually be incorporated under Fair Use laws as long as you don't copy the existing format. Try to use JEDEC standards where they are availible. They are fairly consistent about the variable naming and usually include many parts in the same document. One data file that defines 10 parts is easier to handle than 10 files that define 1 part. There can be some confusion as to the length vs. width of the part. The part is to be oriented with pin 1 in the upper left corner or top center (for PLCC and oddball QFPs). For two lead parts, pin 1 is on the left. For diodes, pin 1 is the cathode. For other polarized parts such as capacitors, pin 1 is on the positive lead. For BGAs, pin1 is on the upper left. The standard may show the part rotated 90 degrees. For two sided parts, specify lead_span_2 instead of lead_span_1. Here is the Spreadsheet and CSV data, not including the extra files.

Due to poorly conceived standards, limitations of the gschem package itself, and GPL fanaticism, these symbols are not usable. GPL license prevents most commercial uses or even free uses where the creator wants to release the project under a more reasonable license. Gschem schematic symbols are based on a preposterous 0.3" pin spacing. At that pin spacing, you can't fit enough of a schematic on a sheet of paper to make a compehensible schematic for circuits of any reasonable complexity. In fact, many of the parts I use would not fit on an 8-1/2x11 or even 11x17 sheet of paper even without connecting components. Even worse, they used a 0.3 mil pin spacing but didn't use 0.3 mil grid so the symbols can't be reduced to 0.1" grid (even though I wrote a program to do so). Symbols based on a 0.1" spacing can be scaled up but 0.3" symbols can not scale down. Symbols drawn at the more common 0.1" lead spacing are quite readable and can even be read when reduced 2:1 on a 600dpi laser printer. gschem doesn't support pinswapping information, either for simple cases such as gates or more complex cases where you need to swap output pins when you swap the corresponding input pin. gschem does not support demorgan equivalents. gschem makes the user act as janitor, positioning all the invisable pin attributes. Does not handle power pins properly.

If you haven't been working with surface mount parts, you may be surprised to know that the naming conventions are extremely sloppy. You could order two 100-PQFP parts and end up with different size compnents. There are multiple body sizes, thicknesses, and lead pitches. There are at least 6 different 100 pin combinations, not counting the presence or absence of heat sinks on the bottom of the chip. I am using the ISO-7351 naming convention which takes some of the ambiguity out. However, it still does not include part thickness or the presence or absence of heat pads. The part thickness is important for 3D models of PC Boards and the presence of heat pads is important because you need to make a matching solder pad on the PCB. I added a "T" on to the beginning of some of the names so that parts with different thickness would have different numbers and am currently ignoring the presence or absence of exposed heat pads. So, a 100 pin plastic quad flat pack could be called "PQFP100", "PQFP-100", "100-PQFP", "100PQFP", "LQFP100", "LQFP-100", "100-LQFP", "100LQFP", "TQFP100", "TQFP-100", "100-TQFP", "100TQFP", "BQFP100", "BQFP-100", "100-BQFP", "100BQFP", "QFP100", "QFP-100", "100-QFP", or "100QFP" But those names are used sloppily and don't really tell you what part you are dealing with. Variations with the dash and with the number after the letters are more common.

JEDEC is an electronics industry standards body. They make many of their standards availble for free download. They also sell hard copies for $350. There is a search engine for finding standards and there is also a table of contents on the JEP95 Main Page Unfortunately, they did not standardize names for surface mount packages and if you search on popular names you may not get a match. Throughhole transistor and diode packages are named after the appropriate standard. I.E. The document TO-220 describes the dimensions of the popular TO-220 transistor package and DO-41 documents the diode package by the same name. JEDEC allows almost all of their documents to be downloaded for free but they can not be redistributed and you can't link directly to the documents on their website.

I would love to hear from any manufacturers who are interested in releasing symbols or other data to this project or at least in a compatible format. There are a number of potential advantages for the vendor. Lack of availiblitly of schematic symbols and footprints is a significant deterrant to deploying new parts. By supporting one format, you will really be supporting many. We can already convert into 4 different CAD formats and expect to add many more. Free advertising. Web site integration. I am willing to work with manufacturers to integrate the conversion programs with their web sites so that you can create links on the component pages to download symbols in any format. And, you can generate graphics for inclusion on the page, such as an image showing all the packages availible for a part side by side at the same scale. If you have symbols in which can be exported in any documented machine readable format (prefereably ASCII based), I would like that data. If you don't have symbols but have databases with information such as: Part and package information Pin number and pin label information Package dimensions with tolerances Spice, VHDL, or Verilog data I would be interested in receiving such information.
