It is known that test power can be more than twice the intended power dissipation of the chip in the functional mode, for a single die. This problem is exacerbated when more than one dies are stacked on top of each other in a single package. Without proper test strategies, the thermal limit could be exceeded during test and this could permanently damage the possibly good chips. Using a heuristic approach, we proposed a set of rules that need to be followed when scheduling the core tests of each chip layer. These rules are based on the initial findings of 3D-chip test simulation using a commercial thermal simulation tool. Using these simple rules, it was found that up to 40 reduction in the peak temperature can be achieved when the thermal-aware test scheduling technique is employed. © 2010 IEEE.
