Mar 1, 2025

In March 2025, delivered a focused set of coverage data processing and dashboard pipeline enhancements for chipsalliance/Cores-VeeR-EL2. Replaced the custom split_info.py with info-process to standardize line/branch coverage extraction, enabled conditional coverage reporting for Verilator simulations to improve accuracy, and compressed coverage data to optimize embedding in the coverage dashboard. Additionally, adjusted coverview build/clone order to speed CI data transfer and processing. These changes reduce data footprint, improve visibility of coverage metrics in CI, and accelerate dashboard refresh times. Business value includes faster feedback loops for verification, more reliable Verilator coverage signals, and lower CI resource usage. Technologies/skills demonstrated include Python scripting, CI/CD automation, data compression, Verilator integration, and dashboard integration.
