#131968 - Thanks for advice
Responding to: ???'s previous message

I really hate the idea of "pull a counter module from the library,"

Still learning, but I'm very inclined to agree on this. It seems much easier to describe behavioural aspect of circuit than to try to make structural approach. I've made few simple examples (counter, shift register) as an exercise, but first time I've tried to make anything more complex with them, I've run into structural/timing problems and my code became cumbersome. It was much simpler to describe bihevioural aspect than to 'glue' predefined modules together. I don't know whether this can be expanded on more complex issues, but from this perspective it certainly does look so...

Regarding the latter, the simulation (or emulation) tool: I use ModelSim with VHDL (or Verilog) test-benches.

Thanks for the tip, I'll try to peek at one :)

That's a fool's errand, also called "Burn And Crash."

Uh... Seems I should not believe to marketing :) I don't honestly see how you can do such a thing. Without any kind of simulation it is like you write a program that you never try prior to shipping it...

Yes, comprehensive test benches take time to write.

Hm, so far I've neglected a bit this part of design, and focused to learn language specifics. I've done only simple clk/signal transitions and watched output... Thanks for advice!

Best luck
