[otbn,dv] Add functional coverage for multiple errors This patch defines coverpoints and crosses to track the multiple error cases documented in the previous one. It also does some refactoring for computed values in the covergroups. For example, SW and LW need to compute an address from and some immediate bits plus an operand value and all the "$signed(operand_a) + $signed(offset)" stuff was getting rather hard to read. Factor it out into the callsite for the covergroup's sample method. The nicest thing would be to have a local variable in the sample method itself, but it doesn't seem that the SV spec allows that.

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
