Advanced UVM Topics

What this section covers

Block-level demos become production environments when you can extend VIP without forking it, end tests precisely, reproduce any failure, configure regressions from the command line, and keep nightly farm runtime under budget. These six topic hubs — each with nested sub-lessons — cover that machinery.

Topics and sub-topics

1. UVM Callbacks — 6 sub-lessons from callback types to VIP API design.

2. Objection Hierarchy & drain_time — 6 sub-lessons from propagation to hung-phase debug.

3. IEEE 1800.2 vs UVM 1.2 — 5 sub-lessons on standardization and portability.

4. uvm_cmdline_processor — 5 sub-lessons on built-in plusargs and regression matrices.

5. Regression Seeds & Reproducibility — 5 sub-lessons on control, logging, and replay.

6. Simulation Performance & Memory — 5 sub-lessons on profiling and TB overhead.

Key takeaways

• Callbacks extend behavior; objections end phases; CLI and seeds scale regressions.

• IEEE 1800.2 is the normative base library — learn it for portability.

• Profile before optimizing — logging and object churn dominate most UVM TBs.

How to use this section

Open a topic hub for an overview and diagram, then drill into sub-lessons for theory, walkthroughs, and code. The course index on /topics/uvm lists every nested page.
