Abstract [en]

High working temperature and process variation are undesirable effects for modern systems-on-chip. The high temperature should be taken care of during the test. On the other hand, large process variations induce rapid and large temperature deviations causing the traditional static test schedules to be suboptimal in terms of speed and/or thermal-safety. A remedy to this problem is an adaptive test schedule which addresses the temperature deviations by reacting to them. Our adaptive method is divided into a computationally intense offline-phase, and a very simple online-phase. In this paper, heuristics are proposed for the offline phase in which the optimized schedule tree is found. In the online-phase, based on the temperature sensor readings the appropriate path in the schedule tree is traversed. Experiments are made to tune the proposed heuristics and to demonstrate their efficiency.
