Design of an Optimal Test Access Architecture Using a Genetic Algorithm
Test access is a major problem for core-based systemon-chip (SOC) designs. Since cores in an SOC are not directly accessible via chip inputs and outputs, special access mechanisms are required to test them at the system level. One of the most important issues in designing a test access architecture is testing time. Here, several issues related to the design of an optimal test access architecture with the goal of minimizing testing time are discussed. These issues include the assignment of cores to test buses, the distribution of test data width between multiple test buses, and the estimation of test data requirements to satisfy an upper bound on the testing time. Previous works [5] show that all of these problems are NP-complete. Here, we applied a Genetic Algorithm (GA) to solve these problems. Experiments were run on two hypothetical but non-trivial SOCs using the implemented GA. The results show a 40% improvement in comparison to results from [5]. The performance improvement is pri...
