[dv/chip] shadow_reg regression fix Recent regression shadow_reg failures are due to reset in shadow_reg sequences. Original code directly used `dut_init` task to issue reset. But in `chip_common_vseq.sv` we override the `apply_reset` task. So this PR: 1). Change the `dut_init` task to `apply_reset` in shadow_reg sequence 2). Because csr_rd in shadow_reg sequence is non_blocking, add a "wait_max_outstanding_item" between each read to ensure no outstanding access exceeds max. Also add a "wait_no_outstanding_access" to make sure all reads are done before going to next iteration 3). Change from verbosity `UVM_LOW` to `UVM_MEDIUM` to reduce the amount of code printed in daily regression 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.
