Eliminating the Verification Bottleneck through Deterministic Intelligence.
nexuSys by PurpleCode AI Systems is the next-generation EDA Platform for RTL debugging and formal verification. Shorten your design cycle with AI agents that reason through hardware logic — deterministically.
Verification consumes ~70% of your design cycle.
Every modern SoC team faces the same gravity: testbenches grow faster than specifications, coverage closure stalls, and corner-case bugs slip past tape-out. A single post-silicon respin costs millions and months.
Manual testbench → Autonomous sign-off.
nexuSys closes the gap between hand-written stimulus and deterministic verification closure. Agents read your RTL, reason about protocol intent, and surface failures with cycle-accurate traces — not probabilistic guesses.
- Cycle-accurate reasoning, not pattern matching
- Reproducible bug traces with VCD anchors
- Coverage closure assistance, not replacement
nexuSys — verification that thinks in cycles.
Drop-in agents for the verification engineer. No replacement of your flow — augmentation of your sign-off.
Agentic RTL Analysis
Multi-agent reasoning over Verilog and SystemVerilog. Predicts corner-case failures before simulation, surfacing race conditions, X-propagation, and unreachable FSM states.
Protocol Aware
Native intelligence for AXI4 / ACE / CHI bus protocols and the full RISC-V ISA — including indigenous Shakti and Vega cores. Spec-driven check generation.
Seamless EDA Bridge
Integrates with industry-standard simulators and waveform viewers. VCD/FST ingestion, UVM hooks, and CI-native sign-off reports — drop into your existing flow.
Multi-agents One deterministic verdict.
Watch nexuSys orchestrate parallel reasoning — catch failures, auto-repair, re-prove, then ship the tape-out report.

Slack met
▸ Verdict: All five nexuSys agents converged with deterministic traces. 5 findings surfaced and auto-repaired in-loop — 0 escalated to engineer. Coverage targets met, formal proofs closed, no CDC violations, timing slack positive. SoC is cleared for RTL→GDS synthesis.
The Nigamana Engine — formal reasoning for silicon.
The Nigamana Engine is the proprietary reasoning core powering every nexuSys agent. It models RTL as a first-class formal artifact — not text — enabling cycle-accurate inference, automated counter-example synthesis, and bidirectional sync between specification and implementation.
- Cycle-accurate reasoning
- Symbolic state-space exploration with bounded model checking, not statistical heuristics.
- Automated bug-trace analysis
- Root-cause localization in seconds. Every assertion failure ships with a minimal VCD.
- Documentation-as-code sync
- Spec drift detection — nexuSys keeps your micro-architecture docs and RTL in lock-step.
- Verifiable provenance
- Every conclusion is auditable. No opaque generation.
First-class support for the India Semiconductor Mission and indigenous RISC-V cores — Shakti, Vega, and beyond. Verification fluency where it matters.
Your IP. Your environment.
In silicon, leaking RTL to a public model is a fireable offense. nexuSys is engineered for hosted-but-isolated deployment — the Nigamana Engine lives inside hardened, air-gapped data centers, and your design IP never leaves your perimeter unless you explicitly stream it in.
Client-Side IP & ISA
RTL, testbenches, and ISA artifacts are pulled on demand from your infrastructure via a thin signed agent. Nothing is mirrored or persisted at rest on PurpleCode systems.
Strict Tenant Isolation
Per-customer compute, per-customer key material, per-customer storage namespace. No shared inference pools, no cross-tenant embeddings, no cohabited memory.
Air-Gapped Engine Hosting
The Nigamana Engine runs on PurpleCode-managed infrastructure inside top-tier (Tier III+/IV) air-gapped data centers. No public internet path to the model plane — egress whitelisted to client tunnels only.
