DfiiBridge

This tool provides a Python based server that enables you to connect to your Virtuoso sessions and control it remotely using SKILL and Python commands. It is based on the public SKILL bridge (https://github.com/unihd-cag/skillbridge). But there has been some major changes:

• Authentication added
• Improved session management (multiple hosts, search and filtering options)
• Keep Cadence camel case naming
• Introduced c++ SWIG to support other languages than Python (currently only perl is available as well)
• Improved logging
• Added reverse communication channel (calling Python methods from Skill)

Installation

Prerequisits:

• cmake 3.14
• gcc >=10.3
• libzmq
• swig

To run the component tests, just call:

tox

This command creates a new virtual python environment and installs the DfiiBdrige there.

Getting started

Start Virtuoso. Load the dfiiBridgeClient.il, dfiiBridgeServer.il and dfiiBridgeUtils.il in the CIW. To start the Virtuoso server call:

DfiiBridge_startServer()

To connect to the Virtuoso session and get the workspace object, open a terminal inside of Virtuoso and call the following python commands:

from dfiibridge import VirtuosoSessionManager

vm = VirtuosoSessionManager()
ws = vm.get_workspace()
ws.skill.println("Hello World")
