    Using Flip-Flops in CUPL on a 16v8 GAL

    Wincupl is a sort of primitive vhdl, but I have now figured it out. I just had to append ".d" to my output variables, then attached my clock to pin #1 and ground pin #11. And yeah I did have to get intimate with the GAL16v8 and WinCUPL documentation to figure it all out.

    Using Flip-Flops in CUPL on a 16v8 GAL

    I am having trouble understanding how to use the flip flop in GAL 16v8, being programmed with WinCUPL. I have the logic equations figured out for my flip flops and I understand the the extension on a variable is .d for a d flip flop (which I want to use) , but what about the clocks, presets...

    4-bit binary to decimal into dual 7 segment displays

    I think I have figured out a fairly simple way to do it. I intend on using the block method of stopping input above 9 to the BCD Decoder as described above. I will post my result upon completing the circuit and testing it. Thanks for everyones help.

    4-bit binary to decimal into dual 7 segment displays

    How about for displaying the digits 10, 11, 12, 13, and 14? I know how to get the 1's onto the second display. What can I do to get the 0,1,2,3, and 4 to look right instead of how the output is displayed in the attatchment to this post?

    4-bit binary to decimal into dual 7 segment displays

    I am building a simple 3-bit adder that will add two 3-bit numbers together. The result is then display in decimal format onto either one or two 7 segment displays. The highest number that will be displayed is 14. I already have the adder logic setup and all is good as far as that goes. I...
