AgentIC: Autonomous AI Chip Design Agents

An open-source multi-agent system that turns a natural-language chip description into RTL, verification artifacts, timing constraints, and — when PDK + EDA tools are available — GDSII.

Built on CrewAI with specialized agents for architecture, RTL design, verification, testbench generation, STA/SDC, and documentation.

Quick Start

pip install agentic-ic
agentic build --name counter --desc "8-bit counter with active-low reset"

Requires Python 3.10+, an LLM API key (OpenAI, Anthropic, Groq, or any OpenAI-compatible), and OSS CAD Suite for simulation/synthesis.

Architecture

Six CrewAI agents collaborate through a state-machine orchestrator:

Agent	Role
Architect	Writes specification and architecture plan
RTL Designer	Generates synthesizable Verilog/SystemVerilog
Verifier	Lint checks, formal verification (SymbiYosys)
Testbench Designer	UVM-lite / classic testbenches with coverage
SDC Agent	Timing constraints generation
Documentation Agent	Design docs and QoR reports

Pipeline stages: Spec → RTL → Lint → Verification → Testbench → Synthesis → SDC → STA → DFT → Power → Floorplan → Hardening (OpenLane) → DRC → LVS → Post-layout → Signoff

The orchestrator runs bounded correction loops at each stage with retry budgets, strategy pivoting, and checkpoint recovery.

CLI Commands

agentic build --name <name> --desc "<desc>"  Build a chip from description
agentic doctor                                 Check environment
agentic synth --rtl <path> --top <name>        Run Yosys synthesis
agentic simulate --name <name>                 Run simulation
agentic sta --netlist <path> --sdc <path>      Run STA
agentic drc --gds <path>                       Run DRC
agentic lvs --sch <path> --gds <path>          Run LVS
agentic harden --name <name>                   Run OpenLane hardening
agentic report --design <name>                 Generate QoR report

Requirements

• Python 3.10+ (your own venv, not OSS CAD Suite's bundled Python)
• OSS CAD Suite — verilator, iverilog, yosys, sby
• Docker — for OpenLane RTL-to-GDSII hardening
• Open PDK — install via agentic install-pdk sky130
• LLM API key — set in .env or environment

See pipeline.md for the detailed RTL-to-GDSII flow diagram.
