PROFILE

Jan Malek

Worked on verification infrastructure and CI/CD automation for the chipsalliance/i3c-core and chipsalliance/Cores-VeeR-EL2 repositories, focusing on coverage data processing, test reliability, and documentation integration. Delivered features such as standardized coverage extraction, conditional coverage reporting for Verilator, and automated deployment of AXI coverage dashboards. Enhanced CI workflows by introducing nightly and manual triggers, reducing flaky tests with simulation retry logic, and streamlining documentation delivery. Utilized Python scripting, Shell scripting, and GitHub Actions to optimize build systems and automate verification pipelines. These efforts improved feedback loops, increased CI reliability, and reduced manual intervention in hardware verification and documentation processes.

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.
