Tools

We almost exclusively use Open Source-Software to design and code for the Steckschwein.

• cc65 Extensive suite of cross development tools for almost every 6502 based platform. We mostly use ca65 because of the linker. Also, we have a few tools written in C.
• KiCad The best OSS EDA suite. We use it for all things hardware.
• Acme Very nice 65xx crossassembler for almost every platform. We used ACME in the beginning, but moved on to ca65 from the cc65 suite. We still use it for quick-and dirty stuff.
• GALasm Our GAL-based address decoding logic and our wait state generator logic are defined using GALasm, which is an ancient tool, but still very useful.
• Xilinx ISE Xilinx ISE design suite to program the XC9572. The only non OSS development tool we use.
• py65mon We use it’s 6502-emulator/simulator for automated testing using unit tests.
