Mastering Power Integrity: First Get Your Power Distribution System Right

Mastering Power Integrity: First Get Your Power Distribution System Right

I don’t think I’m generalizing when I say that designers working on complex high speed designs really don’t want to expend a lot of time and effort dealing with power integrity problems. And they especially don’t want to do it using tools that are detached from their design flow. In today’s complex PCBs, we’re talking advanced processors, complex FPGAs and superfast memories, which all share various voltage ranges.

Batch Creation of Pin Pairs in Zuken's CR-8000

Tech Tip: Batch Creation of Pin Pairs in CR-8000

Creating pin pairs in the Constraint Browser is fine for one or two nets at a time, but if you want to create pin pairs for a whole design, I recommend using an easy, single-step macro.

Pin pairs of nets other than power/ground nets can be created using a macro command. Pin pairs are needed in the Constraint Browser to obtain values such as “measured route length” and “Manhattan ratio.”

E3.series Off Sheet Connections

Tech Tip: Creating Off Sheet Connections in E3.series

This video walks through the process of creating connections that span more than one page in E3.series. This process comes in handy if your schematic sheet gets too crowded or your signal continues to another part of the schematic. When you assign off sheet connectors, the system understands that the signal continues onto a different sheet(s).

Electrical Design and Yummy Green Chicken

Electrical Design and Yummy Green Chicken

The burning question here (no pun intended) must be, “What does chicken have to do with electrical design?” and in truth, the answer is absolutely nothing! The thought of Green Chicken came to mind because of the warm days in the middle of winter – I wanted to fire up the barbeque. Many of my camping trips and barbeques would have been less memorable without the inclusion of this dish. If I am going camping with my friends, it is automatically expected that Green Chicken will be on the menu. Having said that, there are some great parallels to be drawn between cooking and design, give this recipe a try and let me know how it turned out.
