[prim] Avoid an apparent combinatorial loop in prim_secded_*_dec.sv
Verilator tracks combinatorial loops by variable, not by bit. Thus, it
sees a loop with the code that was there and generates an UNOPTFLAT
warning. Pull the shared ^syndrome_o calculation out into a separate
variable to fix things.
Running secded_gen.py was a bit painful. For next time I need to
figure this out:
git grep secded_gen.py -- '*dec.sv' | \
grep -v hamming | \
cut -d ' ' -f 3- | \
xargs -n 8 util/design/secded_gen.py

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.
