The Pipeline

8 stages. Fully automated.
Intent to verified silicon.

Each stage is powered by specialised AI agents that generate, review, and refine — delivering production-quality output at every step.

01

Requirements

Natural language briefs into structured, testable requirements

02

Architecture

Subsystem decomposition with clock/reset domains and interconnects

03

IP Hierarchy

Top-down IP decomposition with intelligent reuse

04

Micro-Architecture

Ports, registers, state machines, CDC plans, timing constraints

05

SystemC Modelling

IEEE 1666-compliant functional models for early validation

06

RTL Generation

Lint-clean, synthesizable SystemVerilog with Verilator refinement

07

Verification Planning

Test plans, coverage goals, and VIP selection

08

UVM Testbench

Complete UVM environment — agents, drivers, monitors, scoreboards

Design Intelligence

Smart requirements.
Smarter design decisions.

AI-powered requirements management, spec processing, and full design traceability — from first brief to final deliverable.

Requirements Management

AI-generated requirements from product briefs. Approval workflows, version tracking, bulk operations, and acceptance criteria.

Spec Processing

Upload PDF datasheets and specs. AI-powered extraction, structure indexing. PDF, TXT, MD, DOCX support.

Design Intent Tracking

Capture intent across all stages. Link decisions to requirements. Full traceability from requirements to RTL to testbench.

Register Design

SystemRDL 2.0 automated register maps. Field-level definitions, interrupt registers, overlap validation.

RTL Editor

Syntax-highlighted SystemVerilog with Monaco. File tree navigation, iteration history, inline Verilator results, code diffs.

Export & Deliverables

PDF documentation, RTL ZIP bundles, Markdown requirements, Git auto-commit, full traceability matrix.

Intelligence

Your priorities shape
every design decision.

AI extracts intent from your product brief — explicit, implied, and silent gaps — then adapts every downstream stage to match your priorities.

Correctness

Reliable, bug-free operation. Formal requirements, exhaustive verification, and coverage closure.

Simplicity

Fewer blocks, reduced complexity. Merge related logic, coarser granularity, simpler access patterns.

Area

Small silicon footprint, minimal routing overhead. Compact encodings, minimal block count.

Power

Low energy consumption. Power domain grouping, clock gating, burst-and-sleep buffer sizing.

Performance

High throughput, low latency. Fine-grain parallelism, larger buffers, separate data/control paths.

Full Traceability

Priorities flow through every stage — from requirements to architecture to RTL. Reviewers calibrate severity based on your goals.

How it works: You rank your priorities in the product brief. AI captures explicit intents, infers implied requirements, and documents silent gaps. Every decision — subsystem count, clock domains, buffer sizing, register design — adapts to match. Reviewers adjust thresholds accordingly.

Libraries

139+ protocols.
Verified building blocks.

Industry-standard protocol support and a library of verified primitives — CDC synchronizers, FIFOs, arbiters, and more.

AMBA

AXI4 AXI4-Lite AXI-Stream APB AHB

Peripheral

UART SPI I2C USB PCIe

Handshake

Valid/Ready Decoupled Irrevocable

Memory & NoC

SRAM ROM DRAM Packet-Switched Credit-Based

Verified Primitives

CDC Synchronizers Async FIFO Sync FIFO Round-Robin Arbiter Priority Arbiter Barrel Shifter CRC ECC Hamming Address Decoder Ping-Pong Buffer

Quality

Built-in quality at
every stage.

A 5-layer validation framework with human-in-the-loop approval, creator-reviewer AI patterns, and iterative refinement.

Human-in-the-Loop

Review and approve AI outputs at every stage. Quality gates, audit trails, per-requirement and per-stage approval with notes.

Creator-Reviewer Pattern

Every stage runs generate → review → revise loops. Up to 3 iterations with severity-classified findings. Graceful degradation.

Validation Framework

5-layer validation. Protocol compliance (8 checks). Verilator iterative refinement (3-5 iterations). Quality reports with full traceability.

Coverage Targets

>95% functional coverage. >90% code coverage. Automated coverage-driven verification closure.

Issue Tracker

AI crews report and resolve issues during execution. Human review at every stage. Full visibility into what was found, fixed, and flagged.

Standards

Industry standards.
Built in, not bolted on.

Every output is validated against the standards your team already works with.
