Testbench : HowTo


I am new to TinyFPGA and solved to program the BX with the sample program and also did some modifications. Very fine.
But if I use the sim in Apio I get the following error message:
Error: no testbench found for simulation
What does that mean? Is there some description what I need to do? Manual?

thanx for help in advance.


It means you do not have a top_tb.v file. You need the tb (testbench) file to run simulations.

Here is a not very good one for blinky:


Everything fine. Works. Thank you
