Boundary Condition Test
Overview
Boundary condition test is a verification technique employed within the NISA-DV framework for verifying neuromorphic ISA (instruction set architecture) extensions on RISC-V-based processors. It is presented alongside random test and directed test methods as one of the core test-generation strategies used to address the shortcomings of classical random verification on emerging neuromorphic architectures.
