Just to be clear, ogurksjnv, we are specifically aiming for RV64GC
compatibility (legal issues notwithstanding). We are going to be
implementing additional standard/custom extensions as well, one of which is
SimpleV (or some variant thereof). We are planning on implementing the S
extension from the privileged spec.
We will most likely implement either the B extension or some similar custom
extension (only if the B extension is not ready in time).
We are most likely going to not implement the V extension.
We will be testing our processor, and, most likely will use formal methods
to mathematically prove that we implemented the processor and memory system
