[otbn,dv] Avoid spurious MOD read entries in trace
If OTBN reset in the middle of a BN.ADDM or BN.SUBM then the second
term of the expression for ispr_read[IsprMod] stayed true while we
were in reset (because it depends on a non-reset flop), causing a
spurious
< MOD: 0x00000000_000...0000
line once we started OTBN again after the reset. The fix is simple:
just qualify that term by insn_fetch_resp_valid. (Other terms are
qualified with that already because it's part of any_ispr_read).

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.
