PROFILE
Phani Peri
During a three-month period, P. Peri enhanced the reliability and validation throughput of the lowRISC/opentitan hardware verification environment. They upgraded the CSRNG testbench using SystemVerilog, introducing a dedicated under_reset flag and new configuration options to improve hot reset handling and reduce test stalls. Peri also addressed reliability issues in the alert-handler by implementing an event-driven trigger for alert and ping monitoring, which reduced spurious reactions in nightly builds. Additionally, they hardened the Power Manager’s escalation clock timeout logic by adding a dead-cycle counter, leveraging SystemVerilog Assertions and hardware design skills to improve security-critical timing and nightly test stability.

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).
