Testing a system-on-a-chip with embedded microprocessor
Rochit Rajsuman · 2003
In this paper, we describe the test methodology for embedded cores based system-on-a-chip (SoC) which contains a microprocessor core. First the microprocessor core is tested for correctness of all the instructions and then the computation power of the microprocessor core is used to test the on-chip memories and other cores, A small Iddq test set is also used to detect physical defects. The design features to facilitate Iddq testing are described.
