Embedded processor testing techniques based on the execution of self-test programs have been recently proposed as an effective alternative to classic external tester-based testing and pure hardware built-in self-test (BIST) approaches. Software-based self-testing is a nonintrusive testing approach and provides at-speed testing capability without any hardware or performance overheads. In this paper, we first present a high-level, functional component-oriented, software-based self-testing

Then, we validate the effectiveness of the proposed methodology as a low-cost alternative over structural softwarebased self-testing methodologies based on automatic test pattern generation and pseudorandom testing. Finally, we demonstrate the effectiveness and efficiency of the proposed methodology by completely applying it on two different processor implementations of a popular RISC instruction set architecture including several gate-level implementations.
