Oct 1, 2025October 2025 monthly summary for Purdue-SoCET/RISCVBusiness focusing on reliability and correctness improvements. Delivered two major robustness enhancements in the RISCVBusiness stack: Bus Controller Robustness: L2 Error Forwarding in the writeback path; Cache Coherence Robustness: Decouple Tag Writes to prevent edge-case false snoop responses. These changes improved verification accuracy, memory operation safety, and overall system reliability, reducing risk of data corruption and flaky tests.

Apr 1, 2025April 2025 (Purdue-SoCET/RISCVBusiness): Improved reliability and observability in the RISC-V pipeline through interrupt handling stabilization and hardware performance monitoring. These efforts deliver measurable business value by reducing interrupt-related memory-operation hazards and by enabling detailed performance analysis via new cache-miss metrics and CSR exposure.
