CHIP DESIGN REFERENCE FLOW
This folder contains the recommended directory structure for implementing ASICs using OH! The directory structure is based on two decades of chip design experience (from 0.35um to 14nm) and is currently being used by Adapteva to design Epiphany based ASICs.
The structure is designed to simplify implementation scripts and maximize portability across:
- multiple foundries
- multiple process nodes
- multiple IP vendors
- multiple EDA vendors
