[SOLVED] Problems with writing UVM test for GPIO UVC

Hello!

I'm new with UVM and I'll be grateful if anyone could help me to solve the problem with executing test written with SV.

I use the example code of GPIO UVC from Cadence Inc. In addition, I've written my own test library, testbench and test_top module for simulation (shown below). But after starting test with ncsim, I got this information from log file and didn't get any waves for chosen signals. I suppose that UVC can't create any sequences for sequencer. May be anyone know what the cause of this is?

SVSEED set randomly from command line: 936318831

I am not familiar with the GPIO UVC but it seems that the test shuts down after zero time.
The first thing to check is do you have a sequence, have you connected it to the GPIO sequencer and does
the sequence raise an objection until it finishes the body

Thanks, meir, for your advice! It turned out that the sequencer didn't get sequenses properly
