3.3 · UVM scoreboard compare() and uvm_error — UVM Class

What you practice

UVM scoreboard compare() and uvm_error (3.3). Compare expected and actual FIFO transactions and raise uvm_error on mismatch. It is in Scoreboard — Part 3 · Env and Coverage of the UVM Masterclass. Assemble the verification environment, compare data, and hunt coverage.

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

Open the UVM workspace in the IDE. The DUT and the testbench compile together in the browser.
Run the SystemVerilog simulation with Verilator and read the phase and scoreboard lines in the log.
When the check is on pins rather than a print, open the VCD next to that log.
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 UVM scoreboard compare() and uvm_error. Change the source, run the Verilog simulator again, and read the waveform without leaving the IDE. Simulation guide · Yosys guide.
