[kmac] Remove entropy refresh timer This commit removes the entropy refresh timer. The timer introduces complex modeling in the KMAC scoreboard and does not help the security model much. The design is changed to: - Remove the entropy timer entirely - Introduce SW triggered EDN refresh request - Increase EDN wait timer to support more than 5ms wait, which is the maximum wait time to be expected. - Add CSR for SW to check the number of Hashing op run Signed-off-by: Eunchan Kim <eunchan@opentitan.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.
