May 1, 2025May 2025 monthly summary for xlsynth/bedrock-rtl: Delivered key feature enhancements and targeted code quality improvements with clear business value. Implemented Flexible Counter Configuration and CDC integration, enabling explicit specification of counter value and change widths and passing EnableAssertFinalNotValid to counters for CDC-related control across push/pop paths and flag management (commits 50c57c647ec4528dcba2a6a1bf34e848aa629145; 5c75e8b21409254dc178a124317490e88f9f558c). Also completed code quality cleanup by removing a redundant rd_data_valid assertion and adding lint suppressions to reduce false positives in reset synchronizer and mock gate modules (commits 636ed6bf0f5e2410221300f2baa36b7d69ac761d; 3fe5bd6eba20281a583706ccbd7057af7d8d48b5).
