Power Conscious RTL Test Scheduling

In the paper, a methodology of power conscious RTL test scheduling is described. The methodology is based on the fact that circuit under analysis (CUA) is partitioned into testable blocks (TB), the information about the partitioning is the input information for the methodology. TBs are mapped into AMI platform, for each TB the sequences of test vectors are then derived, a professional tool is used for this purpose. The sequences of test vectors are then reordered with the goal to reduce power consumption during test application by reducing switching activities. The power consumption estimation is combined with the implemented platform which allows to gain more precise results. The values of TBs power consumption are then used in RTL test scheduling methodology. The goal is to find test schedule with lowest test application time and lower power consumption than the required maximal value.
