Siemens EDA’s Jake Wiltgen explains the difference between transient and permanent faults when designing to the ISO 26262 standard, including where they come from and key ways to protect against them.

Synopsys’ Vikas Gautam points to how the economics of designing large SoCs is driving chiplet-based designs and the need for die-to-die standards such as UCIe, along with the key protocol verification challenges teams face today.

Cadence’s Neelabh Singh highlights key updates of the USB4 Version 2.0 specification, with new capabilities in almost all the layers of the 1.0 specification, particularly focused on how to tunnel and transmit data faster.

Arm’s Madhusudan Rao explains the company’s approach to implementing functional safety through formality and supporting processes such as requirements management, configuration management, change control, and ability to verify the systematic capabilities of the IP.

SEMI’s Serena Brischetto chats with Imec’s Michael Peeters about why the next generation of mobile connectivity could enable massive machine-to-machine communication, holography, and federated learning and why it’s time to start hardware development now.

Ansys’ Jamie J. Gooch, Matt Ladzinski, and Alex Rogers check out how simulation was used to make the NASA-APL Double Asteroid Redirection Test (DART), which aimed to test if it was possible to change the orbital period of Dimorphos around Didymos, a pseudo-stable binary asteroid system, with a kinetic impact.

Coventor’s Pradeep Nanja shows how to model in-situ etch end point detection by building a series of virtual processes containing a virtual etch step, variables, sequences, and loops.

A Rambus writer provides a primer on VESA Display Stream Compression, including why it’s needed as display resolution continues increasing, applications where it’s being used, and visual impacts.

Intel’s Asha Keddy finds that upcoming release of 5G is expected to go beyond performance enhancements to open new use cases by applying AI-based techniques at different levels of the network, such as for network self-optimization and radio interface operation.
