Self testable boards with standard IEEE 1149.5 module test and maintenance (MTM) bus interface

In this paper we present the PMSC (Programmable Module Selftest Controller) chip, which realizes an intelligent module test and maintenance (MTM) bus interface for boards as specified in the IEEE 1149.5 standard. Using the standardized "Reset Module with SBIT" command the PMSC chip performs a complete self test of the whole board, which includes the test of all interconnects and all chips. We support chips with a self test capability as well as chips without self test since the PMSC chip allows on-line test pattern generation and test response evaluation.<
