BOOM Core

Tool

BOOM Core is a BOOM/RISC-V processor core used as a design under test in ProcessorFuzz hardware-fuzzing experiments. The supplied evidence supports its role in BOOM ground-truth bug timing comparisons against DIFUZZRTL configurations and documents two BOOM-related findings: a page-fault bug shared with Rocket and an mstatus.FS dirty-state issue.

BOOM Core

BOOM Core is referenced in the ProcessorFuzz paper as a BOOM processor/core and as a RISC-V processor-fuzzing target. The available evidence focuses on verification and bug-finding results rather than BOOM's implementation details, repository structure, or normal integration flow.
