  1. Read the spec
    Planned 18 requirements and 27 scenarios to test.
    Show the plan

    Single-port AXI4-Lite RAM. Reuse the axil agent; byte-lane reference model; protocol, reset and back-pressure checkers.

    Directed reset and corner-case sequences first, then constrained-random traffic with back-pressure and skew knobs swept, then targeted sequences for any coverage hole the previous pass reported.

  2. Wrote the tests
    First version: tb_v0.sv, a complete UVM testbench.
  3. Round 1: 2 failures
    • Both were bugs already reported.
    Every scenario reached.
    27 of 27 scenarios reached · code coverage 98.4% · simulated in 1 min 37 s
  4. Done: no new bugs. 2 reported earlier still fail.
