Run Simulation

Execute Spectre simulation via virtuoso sim run.

Prerequisites

Simulation must be set up first (see /sim-setup):

• simulator('spectre) configured
• design(lib cell view) set
• modelFile(...) configured
• desVar(...) set for any parameterized variables
• resultsDir(...) set

Run analysis

# DC operating point
virtuoso sim run --analysis dc --param saveOppoint=t --timeout 120 --format json

# Transient
virtuoso sim run --analysis tran --stop 10u --timeout 300 --format json

# AC
virtuoso sim run --analysis ac --start 1 --stop 1e9 --dec 10 --timeout 300 --format json

Important: resultsDir — DO NOT CHANGE

⚠️ The ADE session binds run() to the resultsDir established when the GUI session was first created. Changing it to any other path silently breaks run() (returns nil).

# ✅ Find the canonical path from the runSimulation script
 <netlist_dir>/runSimulation | grep
