Build Status
- CaravelHost: Success
- ExperiarCore: Success
- Flash: Success
- Peripherals: Success
- Video: Success
- WishboneInterconnect: Success
- user_project_wrapper: Error at step 13
- Running Global Routing Resizer Timing Optimizations: Routing congestion too high
Tests
verify-peripheral-rtl (-gl)
Status: Success
Runs a number of tests (currently just a very basic gpio test) from the management core to ensure the peripherals work correctly.
ToDo
- Get it to build
- Flash controller
- JTAG core managment controller
- CSRs
- Write more tests
- Fix all of the errors
Reference work and inspiration
- Zero to ASIC Course: Complete course on ASIC design. Also has useful references and terminology definitions.
- 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. This seems slightly out of date, but an alternate version can be found in the github repository.
- 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.
