Hi Darryl,

I'm looking for a training concerning the rules of how to make stimuli for a work bench.

When I try to simulate with XILINX ISIM, my design stop after a short time.

I want to test my fifo design.

Below, it's the stimuli I need for my testbench.

first, I want reset for 100 ns.

Then, I want WR_EN go hight for continuous time=> in the same time, I need that DATA in's value change from 00 to FF.

4 uS after WR_EN is ON, I want that the RD_EN signal go hight.

Normally, if all the signal are ok, I should see in the RD_DATA, the value I put before.=> valu from 00 to FF.

Next time, I 'll send the screen shot of my bad simulation with wrong signal.

Thank you for your help.

Frédéric.
