What is the meaning of the word “interconnect”? As the word is applied in the field of electronics, interconnect, as defined at, defines the word as follows. “An interconnect (generally speaking) is a physical or logical connection between two electronic devices or networks.” Printed circuit boards (PCB) consisting of hundreds, sometimes, thousands, of interconnected integrated circuits (IC) and other active and passive devices are essential in today’s electronic world.
Since its inception, ScanWorks has provided board-level shorts and opens testing of interconnects between Boundary-Scan devices through use of its Automatic Test Pattern Generation (ATPG) feature. ScanWorks ATPG creates the patterns necessary for shorts and opens testing based on the board topology (i.e. connections between devices) and the Boundary-Scan Cell types on the I/O pins within each device. With recent enhancements, ScanWorks can now generate patterns that can be applied by chip-level automatic test equipment (ATE) to test for shorts and opens in the interconnections between silicon “chiplets” in multi-die devices.
Today, February 15th, 2020, marks the official 30th Anniversary of JTAG. What a wild ride it has been – from its humble beginnings for detecting short and open circuits, it has evolved to be, in some ways, the most powerful and feared technology on the planet. How did we get here?
