Reference work and inspiration
- Riscduino: Used for inspiration and as a reference for using openlane. There are a number of similar aspects to this project, but all have been reimplemented rather than copied.
- Openlane Documentation: Reference for a lot of configuration. The Variables and Hardening Macros pages have been particularity useful.
- Caravel Documentation: Reference for caravel and configuration.
- Zero to ASIC Course: Complete course on ASIC design. Also has useful references and terminology definitions.
