Pruning-based trace signal selection algorithm

Post-silicon validation is an essential part of modern integrated circuit design to capture bugs and design errors that escape pre-silicon validation phase. A major problem governing post-silicon debug is the observability of internal signals since the ...

Incorporating on-chip trace buffers (TBs) helps to overcome the limited observability by tracing selected signals during post-silicon validation. The effectiveness of TB-based techniques largely relies on selection of appropriate trace signals. For ...

In this paper, we propose a differential evolution (DE) algorithm variant with a combination of multiple mutation strategies based on roulette wheel selection, which we call MMRDE. We first propose a new, reflection-based mutation operation inspired by ...
