From rtl-agent-team
Defines simulation tool profiles (Verilator, Iverilog, VCS, Xrun, Questa) with standardized run and replay commands, plus UVM coverage collection guidance.

- Prefer wrapper: `scripts/run_sim.sh`
Runs UVM-based verification on RTL using commercial simulators (VCS, Questa, Xcelium). Outputs test summaries and coverage reports.
Simulates SystemVerilog designs using Verilator. Auto-detects DUT and testbench files, compiles with trace, runs simulation, and outputs structured PASS/FAIL results.
Guides technical evaluation of code review feedback: read fully, restate for understanding, verify against codebase, respond with reasoning or pushback before implementing.

| Simulator | Compile Flag | Runtime Flag | Coverage DB | Merge Tool |
|---|---|---|---|---|
| VCS | -cm line+cond+fsm+tgl+branch | -cm line+cond+fsm+tgl+branch -cm_dir <dir>.vdb | .vdb directory | urg -dir *.vdb -format both |
| Xcelium | -coverage all | -coverage all -covworkdir <dir>/cov_work -covscope tb_top | cov_work/ directory | imc -exec merge.tcl |
| Questa | +cover=bcestf (at vlog) | -coverage (at vsim) + -do "coverage save -onexit <file>.ucdb" | .ucdb file | vcover merge out.ucdb *.ucdb |
Questa gotcha: +cover=bcestf at vlog compile is mandatory — runtime -coverage alone collects nothing.
