[aes] Parameterize LFSR default seeds and perms This commit changes how the LFSR default seeds and permutations for the clearing and masking PRNG of AES are generated and propagated. In line with other OpenTitan IPs, we now use the `gen-lfsr-seed.py` script. The values are exposed as IP parameters. We do not yet expose them to the top-level/`top_pkg.sv` as the type declarations and dimensions are likely to change in the process of SCA hardening. This allows to continue the SCA hardening work without constantly updating the top level. Signed-off-by: Pirmin Vogel <vogelpi@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.
