Bus Blaster v2.5 bitstream(SVF) for XC2C64A-VQ44

June 06, 2013, 09:53:18 pm

Hi everyone,

I have recently assembled my Bus Blaster v2.5. But, I could not find XC2C32A-VQ44 CPLD, so I replaced it with XC2C64A-VQ44. They seem to be pin to pin compatible, but SVF file of XC2C32A-VQ44 did not work with my CPLD. I am new to CPLD/FPGA. I tried recompile buffer logic source with Xilinx IDE with no success. I wonder if someone had used XC2C64A-VQ44 for buffer logic and can share SVF for the latter.

It will need to be recompiled. I can do it, but I don't have the resources here.

When you compiled, what changes did you make? It should be setting the chip in the project file, maybe changing one header, and then export the SVF. There is a complete step by step tutorial for compiling and exporting with the CPLD breakout boards:

Ive just changed XC2C64A in project properties target CPLD from XC2C32A to XC2C64A, in project settings and compiled it. If i recall it correctly, compiler removed few lines. As for header you mentioned, which one should be changed ?
