hib1 0 Report post Posted October 31, 2014 I am using a Papilio one 500 and the logic start one board. I tested the logic start with the test program that exercise all of the leds and switches and every worked. I programmed the same boards with the program "first project" in the book "Introducing the Spartan 3E FPGA and VHDL" by Hamster. I cut and pasted the code and the project built and generated a bit file. No LEDs lit when I moved all of the switches. Does anyone have suggestions on getting this first project to work?

hib1 0 Report post Posted October 31, 2014 I found a missing line in the vhd file. The project works now. Sorry for the trouble I may have caused. Share this post Link to post Share on other sites

Howard1 0 Report post Posted February 14, 2015 sorry, I can't find my records on this. Try proofing the code carefully. also check the ucf file. Share this post Link to post Share on other sites

The way the parser works it will often fail further down on a line that looks fine because the earlier mistake throws the whole works out of whack. Share this post Link to post Share on other sites
