## Known Issues ## Known Issues
- 21/08/2020: Verification passes unconditionally, even in the presence of obvious bugs. This is due to the `rvfi.valid` signal from the CPU being held at constant 0. Suitable instruction and data buses as well as interrupt signals have not been wired to Minerva which is likely preventing the core and verification from functioning properly - 21/08/2020: Verification passes unconditionally, even in the presence of obvious bugs.

- 25/08/2020: Interrupts have been hardwired to zero and instruction/data buses attached to the Minerva core; however, running the verification completely hangs the machine. Possible culprit: huge number of `Assume` statements on memory values leading to overly large solution space - 25/08/2020: Interrupts have been hardwired to zero and instruction/data buses attached to the Minerva core; however, running the verification completely hangs the machine.
