One of the most common outputs from a DC Drop simulation is a current density plot. But how much is too much current density? The answer depends on temperature rise, and requires a PI-thermal co-simulation to properly characterize.
HyperLynx PI does an iterative co-simulation to include the effects of current density on temperature rise, and the effect of temperature on current density and voltage drop, to quickly pinpoint problems in your PCB's power distribution network. This new video explains how designers can keep their PDS from feeling the heat.

In Part 1 of this series, Paul Taubman made the bold statement that the PCB layout is just as much a mechanical effort as it is an electrical one. In Part 2, he threads the needle, explaining why he believes that a PCB truly a mechatronic design, and why mechanical engineers may be more prepared to take on the PCB layout.

Pulsonix has been developing PCB design software for almost 20 years, establishing a reputation for its full-featured, low-cost design tools. Now, the UK-based company wants to break into the US market, and Pulsonix recently showcased its latest tools at PCB West. During the show, I spoke with Business Development Manager Ty Stephens about the company’s latest tools and plans to become a major player in the US market.

Schematic verification is a part of the hardware engineer’s responsibility just as PCB layout verification is an accepted part of the PCB designer’s responsibility. However, with today’s circuit designs becoming more and more complex, time-consuming manual schematic verification is no longer an option. Manual verification of a complex circuit introduces significant risk by not identifying schematic design errors that are, in turn, passed to the downstream processes and ultimately to the fabricated board.
