Embedded software-based self-testing for SoC design
At-speed testing of high-speed circuits is becoming increasingly difficult with external testers due to the growing gap between design and tester performance, growing cost of highperformance testers and increasing yield loss caused by inherent tester inaccuracy. Therefore, empowering the chip to test itself seems like a natural solution. Hardware-based self-testing techniques have limitations due to performance and area overhead and problems caused by the application of non-functional patterns. Embedded software-based self-testing has recently become focus of intense research. In this methodology, the programmable cores are used for on-chip test generation, measurement, response analysis and even diagnosis. After the programmable core on a System-on?Chip (SoC) has been self-tested, it can be reused for testing on-chip buses, interfaces and other non-programmable cores. The advantages of this methodology include at-speed testing, low design-for-testability overhead and application of f...
