[fpga] Reduce noise for AES SCA This commit contains the following changes to reduce the noise during AES SCA experiments: - A delay to the manual AES trigger is added to allow Ibex going into sleep (wfi) before the measurement starts. - The reseeding of AES-internal PRNGs is disabled using a parameter. - In the aes_serial application, the entropy complex (ES, CSRNG, EDN0/1) is disabled. This is only possible as the AES PRNGs aren't reseeded in this setup anymore. - USB, HMAC, KMAC and OTBN clocks are disabled in the aes_serial application.

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.
