Synopsys’ Emilie Viasnoff argues that optical sensors are critical building blocks of autonomous vehicles and that sensor digital twins have the potential to dramatically reduce the amount of field testing needed by using driving simulators for tasks ranging from design and testing to integration and autonomous driving system co-optimization.

Siemens’ Sumit Vishwakarma considers the evolution toward digitally-assisted analog and mixed-signal design to keep up the pace of performance improvements.

Cadence’s Paul McLellan listens in on a talk by James Jaussi of Intel Labs on the transition from electrical to optical I/O, when it makes sense to do so, and how it optical I/O would be deployed in a data center server.

Arm’s Tina Tsou introduces LF Edge, an effort to establish an open, interoperable framework for edge computing independent of hardware, silicon, cloud, or operating system, as well as some of the projects in all stages of development the organization is supporting.

Ansys’ Marc Swinnen looks at how design changes intended to fix IR drop end up damaging timing, which leads to more edits and unintended consequences, and why overdesign is no longer a viable option for getting around potential problems.

SEMI’s Ming-Chang Wu discusses the SEMI E187 specification for cybersecurity of fab equipment and how it aims to define fab equipment procurement cybersecurity requirements and address issues of security depreciation when legacy software reaches end-of-life.
