[dv/alert_handler] Fix regression error Two regression errors related to alert_handler: 1. If reset interrupt esc_cycle cnt, scb prediction might have one cycle off due to reset is async, and we are only counting cycles at negedge clock. 2. SCB is cycle accurate to predict esc_cnt, and currently scb only support sending alert right when it finishes (not wait an extra cycle) I will eventually try to support that in scb, but right now to pass nightly regression, we will use this temp fix. Finally I reduced the runtime for entropy_test. As there are 29 alerts in top-level, it is hard to hit all corner cases by increase the runtime. Need to fine tune and constraints.

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.
