You can build a UVM bench. This part is about running one for years: hooking faults into VIP you do not own, driving a regression from the command line, replaying the one seed that failed, moving between library versions, synchronising components without hard-wiring them, making the verdict trustworthy, and keeping a large bench fast and readable. Every topic is built on the course's DMA bench, and every log is from a real run.
Extend a driver with callbacks, steer a run with any built-in plusarg, replay a seed exactly, and port code between UVM 1.2 and IEEE 1800.2.
Coordinate components with events, barriers and pools; waive or reshape messages with report catchers; guarantee a verdict line; and stop hung tests early with watchdogs.
Keep a big bench reviewable and lint-clean, generate stimulus at scale, and reuse VIP across projects.
Topic | What it covers |
|---|---|
Callback ordering, cost and debug; every built-in plusarg and its traps; random stability and seed replay; the UVM 1.2 to IEEE 1800.2 delta table; measured performance costs. | |
Events, barriers and pools; report catchers and waivers; a custom report server for a guaranteed verdict; heartbeats and watchdogs; transaction recording. | |
Testbench code quality and lint; stimulus at scale, including portable stimulus; VIP and IP reuse across projects. |
