Handshake: item_done() and wave analysis

What you practice

Handshake: item_done() and wave analysis (2.3). Complete the driver handshake with item_done() and analyze timing on VCD waveforms. It is in Handshake — Part 2 · Agent: Driver & Monitor of the UVM Masterclass. Connect software UVM components to hardware FIFO pins.

The UVM bench compiles in that same browser SystemVerilog simulator. You edit the test in the IDE, run Verilator, and read the log beside the waveform.

Run it in the Verilog IDE

1. Open the UVM workspace in the IDE. The DUT and the testbench compile together in the browser.
2. Run the SystemVerilog simulation with Verilator and read the phase and scoreboard lines in the log.
3. When the check is on pins rather than a print, open the VCD next to that log.
4. Edit the sequence, driver, or scoreboard in the IDE and rerun. You stay in the same simulator.

The lesson is done when the simulation matches Handshake: item_done() and wave analysis. Change the source, run the Verilog simulator again, and read the waveform without leaving the IDE. Simulation guide · Yosys guide.
