[dv/sram] implement pipelining test and update scb this PR adds the SRAM pipelining test as laid out in the testplan. in this test, we choose a random mem address and send a series of back-to-back transactions to that address, to stress the internal pipelining and forwarding logic. this requires an overhaul of the scoreboard as the SRAM pipelining logic means that while TL memory requests are handled in-order, the underlying memory macro is updated in an out-of-order fashion, leading to several tricky edge cases. NOTE: this PR depends on #5530 to be merged first, as that contains a fix for an issue uncovered by this test. Signed-off-by: Udi Jonnalagadda <udij@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.
