Safety-Critical Software is Hard

Traditional development cycles for DO-178C and ISO 26262 compliant software take years and cost millions. AI can help—but only with mathematical guarantees.

AI Hallucinations

LLMs generate plausible but incorrect code. In safety-critical systems, "usually correct" isn't good enough—you need provable correctness.

Manual MC/DC Testing

Achieving Modified Condition/Decision Coverage by hand is tedious, error-prone, and accounts for 40% of certification costs.

Certification Evidence

Generating the documentation artifacts required by DERs takes as long as writing the code itself. Traceability is a nightmare.

From Specification to Certified Code

Our pipeline uses AI as a proposal engine and formal methods as the gatekeeper—giving you speed without sacrificing safety.

Define Your Specification

Write formal contracts in ACSL, SPARK, or our intuitive DSL. Define preconditions, postconditions, and invariants that your code must satisfy.

1
// Throttle controller contract @requires(altitude >= 0) @requires(speed >= 0) @ensures(result >= 0.0) @ensures(result <= 1.0) float compute_throttle( int altitude, int speed );
// AI-generated implementation float compute_throttle(...) { float base = 0.5f; // @invariant: t >= 0 if (altitude > 10000) { base *= 0.8f; } return clamp(base, 0.0f, 1.0f); }

AI Generates Candidates

Our fine-tuned models generate implementation candidates constrained by your specification, MISRA rules, and target architecture requirements.

Formal Verification

SMT solvers (Z3, CVC5, Bitwuzla) mathematically prove your code satisfies all contracts. No testing required for logical correctness—it's proven.

; SMT-LIB encoding (assert (=> (and (>= altitude 0) (>= speed 0)) (and (>= result 0.0) (<= result 1.0)))) (check-sat) ; Result: unsat ✓ (proven)
// Generated MC/DC test vectors TestCase tests[] = { {5000, 200, 0.5f}, // A=F {15000, 200, 0.4f}, // A=T {15000, 400, 0.4f}, // B=T // 100% MC/DC coverage };

Automated MC/DC Generation

Constraint solvers automatically generate test vectors achieving 100% MC/DC coverage. Each condition independently affects the decision—proven, not hoped.

Emulation & Certification

Cross-compile to your target (ARM, PowerPC, RISC-V), run tests on cycle-accurate emulators, and generate DO-178C/ISO 26262 certification artifacts.

Everything You Need for Certified Code

A complete toolchain from specification to deployment, built for teams shipping safety-critical software.

Portfolio SMT Solving

Race multiple best-in-class solvers in parallel. Z3, CVC5, Bitwuzla, and Yices compete to verify your code—you get the fastest proof.

  • Automatic solver selection based on problem structure
  • Incremental solving for iterative development
  • Counterexample-guided repair suggestions
  • Timeout handling with partial results
