[dv/cip_lib] devmode fix In the current DV code, if `devmode_en` is set and `addrmiss` happened, cip_lib scoreboard expect design to NOT set tl `d_error` bit. However, in current design, the condition will set `d_error` to 1. The reason this issue has not caused any mismatch is because: in dv we assume `devmode_en` = 0, but in RTL, devmode is internally tied to 1. This PR: 1. Fix the logic that `devmode_en` will trigger `d_error` if `addrmiss`. 2. Temporarily set `devmode_en` to 1 with a TODO note. 3. Comment out the code that drives devmode in tl_error_vseq, and add a TODO to fix it once `devmode_i` is not internally tied off in RTL. Signed-off-by: Cindy Chen <chencindy@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.
