PROFILE
Phani Peri
Over a three-month period, contributed to the lowRISC/opentitan project by enhancing hardware verification infrastructure and addressing reliability issues in critical subsystems. Developed a hot reset handling feature for the CSRNG testbench, introducing a dedicated under_reset flag in SystemVerilog to improve test robustness and validation throughput. Addressed alert-handler reliability by implementing an event-driven trigger for alert and ping monitoring, reducing spurious reactions in nightly builds. Further strengthened the Power Manager by adding a dead-cycle counter and SystemVerilog Assertions to ensure accurate escalation clock timeout detection. Work focused on hardware design, verification, and testbench development, improving nightly test stability and subsystem reliability.

Oct 1, 20252025-10 Monthly Summary for lowRISC/openTitan focusing on reliability and security-critical timing. Key work centered on hardening the Power Manager escalation clock timeout path to prevent false timeouts and ensure robust control logic under clock stress. Impact: Reduced risk in security/control flow and improved nightly test stability for a cornerstone subsystem.

Sep 1, 2025September 2025 monthly summary for lowRISC/opentitan focusing on reliability improvements in the alert/ping monitoring subsystem. Implemented a precise event-driven trigger for alert and ping monitoring within the alert-handler to respond to events associated with active alerts or active pings, addressing issues observed in nightly builds and reducing spurious reactions. The change is captured in commit 510ce35460d0fd4db4c057e6f7faf431eecdd25b ([alert-handler, dv] fixing nightly).
