A SKILL and Python Framework for automating IC design in Cadence Virtuoso with the following goals:
- Bring the capabilities of skill to Python so (ideally) you don't have to write skill code to do EDA in Python
- In those cases where you do need to write skill, make it pythonic
- Softworks: Software and documentation view types in the Cadence Virtuoso IC design environment.
- Data-panels: Export rich data reports from simulation results to pptx slides and xlsx tables
- Morpheus: Generate Maestro test benches in a standard way compatible with an associated data-panels report
- A SKILL standard library of "batteries included" modules
- A SKILL test framework modeled after pytest
- A SKILL TOML config file reader and writer for the TOML standard
- A SKILL package manager
- Define SKILL++ modules
- Import modules into a SKILL++ lexical scope using the top-level "Import" table
- Create SKILL++ packages
- SKILL environment manager using Conda or Pip Python environments
- Seamless execution of SKILL from Python using SkillBridge

Prints out the following when ran in the CIW:
FILE: /path/to/file/test_Str.ils
passed: Test_emptyp
passed: Test_str2bool
passed: Test_str2bool_error
3 / 3 tests passed
Virtue requires Python >= 3.7 and can be installed using several methods:
- Conda
- Pip
- From source
See the installation instructions in the documentation for detailed instructions.
