The Evolution of Digital Twins

BY: BRIAN BAILEY

Semiconductor development has been a longtime user of digital twins, and shift left is resulting in a rethinking of the models being generated and where they may have value.

Digital twins are starting to make inroads earlier in the chip design flow, allowing design teams to develop more effective models. But they also are adding new challenges in maintaining those models throughout a chip’s lifecycle.

The industry long has held the desire to have an executable specification from which implementations can be derived, and this would create the ultimate digital twin. “What if my digital twin was my specification,” asks Serughetti. “If I start modifying it, I start by modifying the specification, and from that I derive the implementation. Unfortunately, I haven’t seen it as something that has been practical to realize so far.”
