power integrity

Automotive ethernet is the latest virtual reference design platform to be added to the family of models developed by Cadence to support its physical-layer IP cores.

Flow draws on existing strengths in Xpedition, Valor, Nimbic and Flotherm among others to optimize 3D design projects and improve cross-disciplinary communication.

Cadence Design Systems has added LPDDR4 support and a topology explorer to its Sigrity lineup for signal and power integrity analysis of PCB-based designs, as well as more flexible licensing options.

To make a high-efficiency power supply XP Power used heat as an additional design variable with an architecture that turns conventional wisdom over one aspect of component reliability on its head.

Two of the custom designs presented at the 26th Hot Chips in Cupertino exemplified the problems caused by increasing power density and the benefits of looking at heat removal at the system level.

Cadence Design Systems has introduced a variant of Voltus that runs transistor-level simulations to check for electromigration and IR-drop problems.

Mentor Graphics has added to its HyperLynx suite a tool that uses design-rule check (DRC) techniques rather than simulation to look for potential signal-integrity problems.
