Overview
Viper is a hybrid integrated circuit design environment. It supports design workflows with both open-source and proprietary software tools. It also natively supports software and generator based circuit design flows in addition to traditional flows.
It supports both open source tools and Cadence Virtuoso with the Virtue package. It is also easily extended to add new tools or integrate with other tools. It manages projects and their shell environment.

Viper Design Environment
EDA environments can be difficult and messy to setup. Viper simplifies this process with declaritive toml configuration files. It also makes tool selection and initialization pythonic by turning them into Python Conda packages and installing them into virtual design environments.
Viper-forge
Viper-forge is an initiative to develop conda recipes to package EDA tools into conda packages hosted on conda-forge.
