[kmac] Revise Assumption of process There was a corner case that can violate the assumption but which is legitimate input. When msg_valid_i and process_i are asserted at the sametime, and if the message is at the end of the block, the state machine doesn't send the keccak_valid_o but triggers keccak_run_o and wait the keccak complete in StMessageWait state. Then after return from StMessageWait state, it proceed to StPad and send following keccak_valid_o. The assumption is revised to check end_of_block and process_latched 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.
