摘要

提出了一种新的加权伪随机测试发生器wPRPG，用于低功耗捕获后发射(LOC)过渡延迟故障测试。通过对测试使能信号分配不同的权重并应用门控技术，实现了低功耗加权PRPG。与传统的逐扫描测试PRPG相比，这种新型低功耗PRPG在LOC延迟测试中可以实现更高的过渡延迟故障覆盖率。

Low-Power Weighted Pseudo-Random Test Pattern Generation for Launch-on-Capture Delay Testing*

A new weighted pseudo-random test generator called wPRPG is proposed for low-power launch-on-capture (LOC) transition delay fault testing. The low-power weighted PRPG is implemented by assigning different weights on the test enable signals and applying a gating technique. The new low-power PRPG can achieve much higher transition delay fault coverage in LOC delay testing than the conventional test-per-scan PRPG.
