A debug interface is needed with single step, read/write regfiles etc.

microwatt has DMI which is needed to do side by side instruction running and comparison.
Comment 2 Luke Kenneth Casson Leighton 2020-08-03 18:41:11 BST
converted microwatt core_debug and added a link to it in issuer.  start, stop reset work.
