PROFILE
Marijn-qbaylogic
Worked on the clash-lang/clash-compiler repository to enhance simulation trace reliability and scalability for multi-clock-domain designs. Focused on improving the dumpVCD functionality by correcting initial value handling and enabling unlimited trace support with multi-character identifiers, directly addressing debugging and verification challenges in large RTL projects. Applied Haskell and functional programming techniques to deliver robust bug fixes and feature enhancements, while also refining VCD output formatting for better readability. Contributed to release management by co-authoring changelog updates, ensuring documentation accurately reflected codebase changes. Demonstrated proficiency in CI/CD workflows, Git-based collaboration, and cross-module integration throughout the development process.

Nov 1, 2025Month: 2025-11 Overview: - Focus: correctness and reliability of debugging artifacts in clash-compiler for multi-clock-domain designs. - Outcome: delivered a targeted bug fix to DumpVCD initial value handling; no user-facing features added. Key features delivered: - DumpVCD: Correct initial values handling across multi-clock-domain designs by removing initial value scaling in normalize, ensuring VCD output aligns with multi-clock domain first clock edges. Major bugs fixed: - DumpVCD initial value scaling issue in multi-clock-domain designs; fix committed (50df0ba4fc33720376a0c837a6f063e38b3f78ae). Addresses #3075; related to #3076. Overall impact and accomplishments: - Increased reliability of simulation traces for multi-clock designs; reduces debugging time and ambiguity; supports safer verification and deployment of multi-clock designs. Technologies/skills demonstrated: - Proficiency with the clash-compiler codebase, VCD generation, multi-clock-domain debugging, and change-tracking practices (commit references and issue numbers).
