Assertions that secure silicon
Avestra Studio
Transform specifications and RTL into sign-off-ready SystemVerilog Assertions using an 8-agent orchestrated pipeline — in minutes, not weeks.
Drop your spec (.pdf, .docx) and RTL (.sv, .v, .vh, .svh) — Avestra generates a complete SVA suite and testbench.
<1% hallucination rate
Avestra is trained on Ashok Mehta's 3 SVA textbooks, 22 US patents, and 35 years of CPU/ASIC/SoC domain expertise — domain intelligence no generic LLM can match. The result is deterministic, auditable output that holds up at sign-off.

From files to sign-off-ready assertions
Six stages, each powered by specialized agents — from spec parsing to final report.
Parses your RTL designs (.sv, .v, .vh, .svh) and specification documents (.pdf, .docx), extracting FSM states, temporal rules, clock domains, and cone-of-influence — building a structured model of your design intent.
Compares the extracted spec model against RTL behavior. Flags undefined transitions, illegal state sequences, missing coverage targets, and timing violations — before any assertion is generated.
Generates production-grade SystemVerilog Assertions — clocked assert, assume, and cover properties with vacuity guards, multi-clock support, and full source traceability back to spec and RTL.
Reviews and tightens assertions for simulator compatibility and coverage completeness. Eliminates redundant properties, fills gaps, and validates output against known-good patterns from the proprietary SVA knowledge base.
Generates coverage-driven SystemVerilog testbenches with UVM-ready architecture, directed tests, and response checkers — targeting the specific coverage holes identified during analysis.
Produces a full session report: all assertions, cover points, inconsistency findings, simulator targets (Questa/VCS/Xcelium), and a trace from every property back to its source in spec and RTL.
Eight agents, one pipeline, sign-off-grade output
Drop your spec and RTL files into Avestra Studio. The orchestrated pipeline runs end-to-end — catching inconsistencies, generating assertions, verifying coverage, and building testbenches — delivering a complete SVA suite ready for your simulator.
- Accepts .pdf, .docx specs and .sv, .v, .vh, .svh RTL
- Detects spec ↔ RTL inconsistencies before generation
- Every assertion traced to its source in spec and RTL
- UVM-ready testbench generated alongside the SVA suite
Everything you need for spec-to-SVA
Eight integrated capabilities across analysis, generation, optimization, and delivery — built on 35 years of SVA domain expertise.
8-agent orchestrated pipeline
Six user-visible steps powered by eight specialized agents under the hood — spec analysis, RTL analysis, RAG retrieval, inconsistency detection, SVA generation, coverage analysis, cross-check, and testbench generation.
Spec ↔ RTL inconsistency detection
Catches missing states, illegal transitions, and timing violations before the first simulation — before you spend hours debugging a broken testbench.
Production-grade SVA suite
Every generated assertion is clocked, vacuity-guarded, and traced to its source in spec and RTL. Multi-clocked and multi-reset designs are supported.
UVM-ready testbenches
Coverage-driven SV testbenches with UVM-ready architecture, directed tests targeting coverage holes, and response checkers — ready to drop into your existing simulation environment.
LLM-agnostic pipeline
Swap the underlying model without affecting output quality or structure. Works with frontier cloud models and self-hosted on-premise inference — keeping sensitive IP in your environment.
Simulator-independent output
Works with Questa (Siemens), VCS (Synopsys), and Xcelium (Cadence). No simulator vendor lock-in — same SVA suite across your full sign-off flow.
Broad input format support
Accepts spec documents as .pdf or .docx and RTL as .sv, .v, .vh, or .svh. Upload files directly in Avestra Studio — no preprocessing or format conversion required.
Proprietary SVA knowledge base
RAG trained on Ashok Mehta's 3 SVA textbooks and 22 US patents — 35 years of CPU/ASIC/SoC domain expertise encoded into every output. Deterministic, auditable, and sign-off-ready.
