[otbn,dv] Fix unknown FIFO output in `otbn_sec_cm` test The generic countermeasure test for `prim_count` manipulates the redundant counter register to check if a fault injected into one of the counter registers gets detected. When this test exercises the counters inside the response FIFO of the TLUL adapter at the instruction memory, the `DataKnown_A` assertion in the response FIFO fails. This is correct, but it prevents the test from checking the countermeasure. This commit disables that assertion for the described test case. Signed-off-by: Andreas Kurth <adk@lowrisc.org>
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.
