- Constrained Random test generation
- Functional Coverage with hooks for UCIS coverage database integration
- Intelligent Coverage Random test generation
- Utilities for testbench process synchronization generation
- Utilities for clock and reset generation
- Transcript files
- Error logging and reporting - Alerts and Affirmations
- Message filtering - Logs
- Scoreboards and FIFOs (data structures for verification)
- Memory models
For current release information see CHANGELOG.md
