一种基于进化规划的系统芯片测试调度方法

A Test Scheduling Method of SOC using Evolutionary Programming

测试调度是系统芯片测试的一个重要方面,它用于确定把芯片上芯核的测试集分配给测试存取机制的方法,以使得总的测试时间最少。文章提出一种基于进化规划原理的测试调度方法,把测试调度问题的可行解用个体表示,由多个个体构成种群,通过种群的进化而得到较优的测试调度方案。

Test scheduling determines an assignment of cores to test access mechanism such that the overall test application time of system on chip （SOC） is minimized. A new test scheduling approach using evolutionary programming is presented in this paper, which uses individuals to represent the feasible solutions of test scheduling, the better scheduling scheme is obtained by the evolution of populations. The partition for the total width of test bus, as well as the assignment of cores to test access mechanism, can be obtained simultaneously. Experimental results show the approach can effectively solve test scheduling in reasonable time.
