A2601 Board Populated

Posted by retromaster on August 23, 2010

I’ve (mostly) finished soldering the new A2601 board. The Xilinx Impact software recognizes the on-board FPGA and Configuration PROM through the parallel port JTAG cable, so I am able to download designs into the FPGA. Just for testing, I’ve uploaded a small design that outputs some NTSC color bars through the composite video port, and it seems to work fine.

It seems some more work needs to be done to get the A2601 FPGA design to work with the new board, though. It has been quite a while since I last worked on this project (judging from the dates on the files, almost three years), and during this time FPGA software (i.e. synthesis, simulation, etc.) has moved on. So I need to remember all the little bits and pieces and fix a few things here and there to make sure that the design works fine in the simulator again (it previously did). Once the design works in the simulator, it should be fine in the FPGA.
