Formal verification that compounds

Every proof should make the next one easier.

Chipster turns verification history into reusable intelligence for future proofs.

Artifacts get reused. The reasoning behind them does not.

VIP, assertion libraries, protocol checkers, proof kits. Teams reuse all of it.

What does not carry forward is the work around those artifacts: which invariant unstuck a stalled proof, which abstraction made the solver converge, why a counterexample was spurious. That reasoning lives in an engineer’s head or a closed ticket, and the next block starts without it.

The fleet mirrors the architecture it verifies.

Assertions & obligations

Generate candidate properties from design context.

Invariants & proof repair

Search for auxiliary facts that help stalled proofs close.

Formal adjudication

Every attempt returns a labeled outcome: proof, counterexample, vacuity, timeout.

The result? Agentic process intelligence.

Every hypothesis, counterexample, lemma, and refinement that contributed to closure becomes part of how Chipster verifies. It gets sharper at your designs with every proof it runs.

Customer-private intelligence compounds with use.

Your verification history stays inside your environment. Chipster specializes to your architectures and your verification practices, and none of it leaves.

Not another “LLM writes assertions” tool.

A design is a hierarchy of blocks, interfaces, and clock domains. Chipster’s fleet takes that same shape: agents are organized around the structure of the RTL under verification, not around a fixed menu of tasks. Change the architecture and the fleet that verifies it changes with it.

Verification topology, shaped by the design

Verification results that compound.

  • End-to-end property generation and formal checking.
  • Invariant proposals that close stalled proofs.
  • Benchmark results across open RTL designs.
  • Representative proof-strengthening result: an invariant that closed a stalled proof.

Bring us a representative RTL block.

We run technical evaluations with semiconductor design and verification teams.
