Simulation/Virtuoso

Introduction

Cadence Virtuoso is a widely used custom electronic circuit design environment. It's also becoming popular for developing photonic PDK models and libraries for electronic-optic co-simulation.

Configuration

Virtuoso can be run on ECI server, or the binary file can be mounted on your own server.

ECI server configuration instructions:

Login to ECI server: ssh -X to username@linux10.engr.ucsb.edu enabling X-window (The node#10 is a 64bit machine. Do not use the default node which is a 32 bit machine).

Configure the .bashrc file as the instruction in https://www.ece.ucsb.edu/its/cadence/download/README, or as follows:

#Set license environment:
export LM_LICENSE_FILE=5280@license.ece.ucsb.edu
#Set path for Cadence IC615:
export PATH=$PATH:/ece/cadence/IC615/tools/dfII/bin
export PATH=/ece/cadence/MMSIM131/tools/spectre/bin:$PATH
export CDS_AUTO_64BIT=spectre

Please use “which spectre” to check if your spectre points to the newer version (/ece/cadence/MMSIM131/tools/spectre/bin/spectre), instead of the old version in IC5141

Run Virtuoso
