Abstract :
We propose a technique integrating test scheduling, scan chain partitioning and test access mechanism (TAM) design to minimize the test time and the TAM routing cost while considering test conflicts and power constraints. The main features of our technique are (1) the flexibility in modelling the systems test behaviour and (2) the support for interconnection test of unwrapped cores and user-defined logic. Experiments using our implementation on several benchmarks and industrial designs demonstrate that it produces high quality solution at low computational cost.
