The purpose of X-Based simulation is to extract the relationship between instruction set and modules. According to the simulation result, the statistical method is applied.

In this paper, we propose a statistical simulation-based approach. At first, a random sequence test template set based on the instruction set architecture of processor is generated. Then the processor is asked to execute by an X-Based simulator. The purpose of X-Based simulation is to extract the relationship between instruction set and modules. According to the simulation result, the statistical method is applied. It guides the test template set to detect internal faults with higher testability. In this approach, the processor is applied under normal functional mode so that processor deeply executes at-speed test without DFT overhead. A real case for 8051 microprocessor is implemented in this paper.
