Latch-up Electronic Design Automation Checks

This article introduces typical latch-up verification techniques to detect and prevent latch-up. These techniques rely on electronic design automation (EDA) tools to deliver the coverage necessary to identify and eliminate latch-up risks. 

What Are External Latch-up and Internal Latch-up?

Overall, latch-up prevention is one of the most important tasks for both foundries and IC designers. Based on the chip design scheme, designers should select proper solutions to eliminate the ILU and ELU risks in chip design, referencing the foundry guidelines and latch-up silicon data to ensure minimal latch-up risks for the product. 

Use of HBM and CDM Layout Simulation Tools

The methodology of the state of the art of HBM and CDM layout simulations tools is described. Two real-life case studies are presented briefly and the outlook towards future developments is discussed.
