API FIRST

Three-language API calling model

Every tool exposes a unified Python / MCP / Tcl interface that Agents can call seamlessly.

PYTHON API

Headless invocation

import ieda; ieda.iSTA.analyze(design="aes_core") — no GUI, pure API-driven.

View examples
MCP

Agent-native protocol

Expose each tool's capability description, parameter schema, and result format via MCP tools.

MCP docs
TCL

Legacy script compatibility

Keep the Tcl interface for classic iFlow scripts, sharing the same iDB state as the Python API.

iFlow

Chain tools into a flow →

Use iFlow to chain point tools into a full RTL → GDS automation flow.
