rtl-p5s-uvm-verify

Run a UVM-based verification environment on the target RTL using a commercial simulator (VCS, Questa, or Xcelium). Outputs: sim/uvm/results/run_summary.log + sim/uvm/coverage/uvm_coverage.xml.

See references/uvm-architecture.md for UVM component hierarchy, phase order, simulator compile commands, and agent template with project naming conventions.

<Use_When>

• Project mandates UVM methodology
• Commercial simulator is available and licensed
• Complex protocol verification requiring UVM sequences and scoreboards
• Constrained-random verification with UVM agents is required </Use_When>

<Do_Not_Use_When>

• Commercial simulator not available (use rtl-p4s-unit-test or rtl-p5s-func-verify instead)
• Simple directed tests sufficient (UVM overhead not justified)
• Open-source-only tool constraint (use cocotb via rtl-p5s-func-verify) </Do_Not_Use_When>

<Why_This_Exists> UVM provides reusable, scalable verification infrastructure for complex designs. When a commercial simulator is available, UVM delivers constrained-random coverage closure that directed testing cannot match for large state spaces. </Why_This_Exists>

Prerequisites

Commercial simulator required:

• One of VCS, Questa (vsim), or Xcelium (xrun) must be available

If prerequisite is missing: WARNING — commercial simulator not found. Use /rtl-agent-team:rtl-p5s-func-verify (cocotb/Verilator) instead.

Execution

Task(subagent_type="rtl-agent-team:p5s-uvm-orchestrator", prompt="Execute UVM verification. User input: $ARGUMENTS")

Do not perform any work directly. The orchestrator agent manages simulator availability checking, UVM environment generation, compilation, test execution, and coverage collection.

Output

• sim/uvm/results/run_summary.log — test pass/fail summary across all UVM sequences
• sim/uvm/coverage/ — merged functional and code coverage data
• reviews/phase-5-verify/{module}-uvm-review.md — UVM verification review with coverage analysis
