FACR 1804 - Fault Accounting and Coverage Reporting to Digital Modules (FACR)

The standard formalizes aspects of fault models as they are relevant to the generation of test patterns for digital circuits. Its scope includes (i) fault counting (ii) fault classification, and (iii) fault coverage reporting across different ATPG (automatic test pattern generation) tools, for the single stuck-at fault model. With this standard, it will be incumbent on all ATPG tools (which comply to this standard) to report fault coverage in a uniform way, thereby facilitating the generation of a uniform coverage (and hence a test quality) metric for large chips with different cores and modules, for which test patterns have been independently generated.
