Abstract
Pseudorandom Boundary-Scan testing of a interconnects within a system (10) is accomplished by first generating a pseudorandom pattern and then filtering the pattern before application to the system to modify values within each pattern that could cause a signal conflict. Each response generated by the system upon application to the system is also filtered to mask non-deterministic values with the response. The filtered response is compared to a set of signatures representing a fault-free condition to detect faults within the system.
