Test Pattern Generation for Digital Integrated Circuits Based on CA-IA-PSO Algorithm |
| |
Abstract: | In order to improve the ability to get rid of partial extreme spot and the diversity in evolution,IA algorithm is imported into PSO algorithm to form IA-PSO algorithm. For the purpose of raising fault rate and shortening test pattern generation time,CA algorithm into is imported IA-PSO algorithm to form CA-IA-PSO algorithm. Finally, single stuck-at fault is adopted and different algorithms is used to the simulation experiment of test pattern generation,the result is that CA-IA-PSO algorithm can solve the problem of test pattern generation more practically and efficiently, especially in large digital circuits. |
