hib1 Posted October 31, 2014 Report Share 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?

hamster Posted October 31, 2014 Report Share Posted October 31, 2014 Send me you project (well the ucf and vhd files) and I will take a look at it for you.Mike Link to comment Share on other sites More sharing options...
hib1 Posted October 31, 2014 Author Report Share 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. Link to comment Share on other sites More sharing options...

ralph Posted February 7, 2015 Report Share Posted February 7, 2015 I have the same problem. What line were you missing? Link to comment Share on other sites More sharing options...
Howard1 Posted February 14, 2015 Report Share Posted February 14, 2015 sorry, I can't find my records on this. Try proofing the code carefully. also check the ucf file. Link to comment Share on other sites More sharing options...
james1095 Posted February 23, 2015 Report Share Posted February 23, 2015 As with the OP, post your code and we can take a look. It's *very* easy to miss a semicolon or put one where it shouldn't be. 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.
