MOSAIC

The Modular Open-source Analog IC Design (MOSAIC) community and projects involve connecting all independent parties working on automated analog design frameworks and workflows to “touch base”- to share the ideas and developments that had previously been fragmented and largely independent. MOSAIC aims to create a structured and modular development environment for analog generators using open-source tools.

Affiliated projects include:

• Layout with Gridded Objects 2 : LAYGO2 (c) Hanyang University NiftyLab
  • SKY130 version: https://github.com/niftylab/laygo2_workspace_sky130
  • Core: https://github.com/niftylab/laygo2/
• AnalogBase : mosaic-BAG2 (c) (1) University Aalto & SAL (2) Thomas Parry & Matthias Koefferlein
  • https://gitlab.com/mosaic_group/mosaic_BAG
  • Being developed to work with either proprietary PDKs & tools or OS tools: XSchem, NGSpice, KLayout.
• Berkeley Analog Generator 3 enabled for open source tools: OS BAG3 (c) IFAT & SAL, Thomas Parry
