CORE-V Wally Test Plan

CORE-V Wally is tested in the following ways:

• Run RISC-V Architecture Compatibility Tests in lock-step against the ImperasDV reference model.
• Run custom tests to cover virtual memory, PMP, privileged unit, and peripherals in lock step against ImperasDV.
• ***pending: Run random tests generated by risc-dv
• Run CoreMark and Embench benchmarks.
• Run performance validation against reference models for the branch predictor and caches.
• Run the TestFloat suite against all precisions of all operations for the FPU unit.
• *** 83.5% coverage of statements, branches, expressions, and FSM states and transitions
• Boot Buildroot Linux in lock-step against ImperasDV.
• Boot Buildroot Linux on an FPGA and run programs.

Running Tests

Detailed Test Plans

The test plans for specific units are lined below:

• Privileged Unit
• Memory Management Unit
• Peripherals
• Branch Predictor Performance Validation
• Cache Performance Validation

Wally is described in an upcoming textbook, RISC-V System-on-Chip Design, by Harris, Stine, Thompson, and Harris.
