[entropy_src hack] This commit will not be merged. It is a temporary hack to allow the sha3 fsm to gracefully terminate. The current issue is that when disabling, the fsm still requests csrng to halt. However, the outgoing "halt" request is qualified with es_enable, this means the halt is never seen and as a result never ack'd. The fsm then is unable to gracefully terminate. This probably implies all the outgoing signals need to be looked at a bit more carefully to see which should be qualified, which should not. Alternatively, the internal fsm checks could further account for es_enable and not do a halt request. Signed-off-by: Timothy Chen <timothytim@google.com>
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.
