The authors introduce a novel method of test generation for microprocessors at the RTL using spectral methods. Test vectors are generated for RTL faults, which are the stuck-at faults on inputs-outputs of the different modules/registers in the circuit, and the vectors are analyzed using Hadamard matrices for Walsh functions and the random noise level at each primary input. This information then helps generate vector sequences. At the gate-level, a fault simulator and an Integer Linear Program (ILP) compact the test sequences.
