IEEE 1800-2017. Interfaces, packages, structs, generate, always_comb, always_ff.

UVM 1.1 & 1.2

Phases, sequences, TLM, factory, concurrent run phases, objections. Mixed-mode support.

UPF Power-Aware

Power domains, isolation, retention, level shifters, power state tables, X-injection.

Analog Mixed-Signal (Basic)

Verilog-A bridge for analog co-simulation.

RISC-V ISS Co-Sim

RV32IM instruction set simulator. Arch tests, firmware co-sim, cross-validation.

PSS-Lite

Portable stimulus for intent-based test generation.

CDC Lint

Clock domain crossing checks. Missing synchronizer detection.

Runtime Agents

8 agents monitoring compile, elaborate, simulate. Diagnostics on failure.

VCD & FST Waveforms

Standard formats. FST compression. GTKWave compatible.

Compiled Backend

IR → C++ → native .so. Incremental recompile with source caching.

SDF Gate-Level Sim
