ABSTRACT:
A base for a multi-chip module that provides for built-in testability. Active test components are embedded in a module substrate. These test components primarily consist of boundary scan cells that comply with the IEEE 1149.1 test standard. The scan cells are connected to each other, and are connected to interconnection paths among chips and to individual chips, thereby partitioning the module into testable partitions. These partitions permit testing of chip interconnections, chip functionality, and module functionality. Scan cell connections may be mask programmable so that the same multi-chip module base can be used for many different multi-chip module configurations.
