README

This is a repository of KiCad schematic symbol libraries developed at XESS.

• Cypress_PSoC.lib contains a few Cypress PSoC 5LP chips.
• Cypress_cy8c5xlp.lib contains all the Cypress PSoC5LP chips.
• gowin_fpga.lib contains all the GOWIN FPGAs.
• Lattice_ECP5_FPGA.lib contains the Lattice ECP5 & ECP5-5G FPGAs.
• Lattice_iCE_FPGA.lib contains the Lattice iCE40 HX, LM, LP & Ultralight FPGAs.
• pic32.lib contains the PIC32 MX 1XX/2XX 28/36/44-pin microcontrollers.
• wch.lib contains the WCH CH54* and CH55* 8051 microcontrollers.
• xess.lib contains a grab-bag of parts, many auto-converted from Eagle.
• xilinx6s.lib contains all the Xilinx Spartan-6 FPGAs.
• xilinx6v.lib contains all the Xilinx Virtex-6 FPGAs.
• xilinx7.lib contains all the Xilinx 7-Series FPGAs (Zynq, Artix, Kintex, Spartan and Virtex).
• xilinxultra.lib contains all the Xilinx Ulatrascale FPGAs (Zynq, Kintex and Virtex).

But I Don't Like How the Symbols Look!

OK, people are picky. Maybe even more picky when they're getting something for free. (There's probably a psychology paper in there, somewhere.)

The good thing is: you can change these schematic symbols! Obviously you can modify any individual symbol using the KiCad schematic symbol editor. But you can also make library-wide changes using the kipart utility as follows:

1. Use the kilib2csv utility to convert one or more of the libraries into a CSV file.
2. Open the CSV file as a spreadsheet and reorder the pins, change pin types, assign pins to different units, etc.
3. Finally, run kipart on the modified CSV file to create your own custom library.
4. Bask in the glory of your own originality.

Some of the schematic symbols in these libraries have changed! If you previously downloaded and used a library, you may find a newer version has differences like rearranged pins. Including a changed library in an existing schematic could cause errors! Either checkout the library that corresponds to the one you've already been using (look at the check-in dates), or verify that the symbols from the new library attach to the correct nets in your schematic.
