Always block in Modelsim

Altera_Forum · ‎11-14-2012

Hi everyone,

I have 2 Always blocks, but one of them does not run. Can you help me make it run?


always
  begin
    // Code runs
  end
always
  begin
    // Code does not run
  end

Maybe defining sensitivity list may help you out:

always@(*)

Which block I defined sensitivity list, it does not run. :confused:

you are using the "always" block in a wrong way.

Always blocks will be evaluated by Modelsim according to Verilog rules. Because you didn't post any actual code, we could only guess about the specific problem. But this isn't a riddle forum.

For the time being, I want to suggest the classical Cummings paper that addresses many problems around always blocks.
