Abstract
A system for testing every one of the signal inputs and outputs (I/O) of a fine pitch multi-chip semiconductor module utilizing a selective netlist, through the intermediary of presently available test equipment. More particularly, the system facilitates the testing of fine pitch multi-chip modules utilizing 1.0 mm ceramic column grid array (CCGA) technology in order to facilitate the use of increased system interconnect capabilities. Additionally, there is provided a method of employing a selective netlist in order to test fine pitch multi-chip semiconductor modules; especially such as, but not limited to 1.0 mm pitch ceramic column grid array (CCGA) modules by employing commercially available test equipment.
