First of all, i'm sorry for my english. I want to make a 7 digit display using verilog. I'll test the program on spartan 3E. An exemple: I know that i need to use frequency divider, but i don't know how to implement the program. I'm beginner in verilog, but i want to learn with exemples.
You've got numerous problems in this code. Not a problem but easier to maintain...Use Verilog 2001 C-syntax for the module ports: module bcd_to_seven_seg ( output reg bcd1, bcd2, bcd3, bcd4, //declaring each 4-bit decoder input din, clk, enable, output reg qout //shift register values ); [

Well it looks like you need to wire a-h to portb0-7 (so you can use a portb interupt on change) Then hook up DM and DL to another two ports! Set all of the above as inputs When the 7 segments are lit the interupt will fire off. Read all of the port values and use these to work out the trip number. Might need a look up t
