Using PSPICE Components in LTspice

A recent post on the PCEA Discord server requested a bit of assistance using PSPICE models within LTspice. Here's a quick video explaining how I usually do this!

For reference, this video shows how to download the PSPICE model for the TI LM293 comparator and import it into LTspice . We then set up a very basic circuit to show functionality.

Webinar Recording: DDR5 Post-Layout Verification: Find and Fix Causes of Failure

I recently presented (another) webinar with EMA Design Automation to discuss DDR5 ! This time the discussion was centered around a live post-layout demo. In the example, I showed the analysis of a board with PowerSI (which, of course, had some failures when the DDR report was generated). We then used S-parameter and TDR analysis to track down the failures. Lastly, we used the Clarity Via Wizard to generate new via models and we used Allegro High-Speed Structures to place them in the layout. Lastly, the board was verified to show a passing report.

Webinar Recording: A Dive into DDR5: An Engineers Guide to Simulating and Validating the Latest Generation of DDR

I recently presented a webinar with EMA Design Automation to discuss DDR5 ! I cover the new features added compared to DDR4 then spend some time showing a demo of Cadence Topology Explorer ( TopXp ) including simulation of a full byte lane with IBIS-AMI models.

Why Buy When You Can Spend More Time and Money Making Your Own?

We've all been there: you've got a problem to solve and are faced with the make versus buy decision. In my case, I wanted to switch a USB peripheral between two PCs; that's the only hard requirement. The easiest solution would have been to simply add a USB hub to my KVM switch and call it a day, but that wouldn't carry USB-3 multi-gigabit data rates (not that I needed to, but I wanted to).

Antenna Analysis from Ham Radio to PCBs

Has anyone else ever thought about why so many engineers are also active amateur radio operators? My theory is that there's just so much passion for the science and practical use of these complex electronic systems! We enjoy the problems, challenges and solutions so much that we want to find other ways outside of work to find those same experiences. In this case, I've got a story that starts with some amateur radio equipment but comes full-circle to address an extremely common design issue. Specifically, we'll look at the Arrow OSJ antenna performance as well as the characteristics of a printed circuit board antenna.
