Hello Gene This would seem to indicate the older VHDL code. The manufacturer, Spectrum Digital, should be able to tell you more about when the manufacturing switch over occured. It was at about the time I left TI. If you can get your hands on (or build... its simple) a programming adapter, I think the FPGA programming S/W is free. The deal with Cypress is that you get a learning VHDL book, target test hardware and programmer. Not a bad deal actually.

I am attempting to develop a daughterboard for the VC33 university DSK. I can't seem to get the ARE and AWE strobes to work. I see them for reads and writes to 0x9FFFFF (I know that this overlaps on-board FPGA), but not for reads and writes to 0xA00000. The VHDL description of the on-board FPGA looks like this should work. Does anybody have any ideas? Is there anyway to tell if the FPGA is up to current rev? Any help would be greatly appreciated. Gene |
