How it works
This project contains a 96bit serial scanchain, and the core of the serv CPU. Signals present on the scanchain are a wishobne bus and the native registerfile interface. As there is not enough room inside the TinyTapeout project area to fit RAM/registerfiles these have to be implemented externally. In theory just a bit of custom code running on caravel will be enough to get the serv core running.
