Altering Trace Widths in Cadence

Background

Why do I need to change my trace widths?

As you start to learn schematic and PCB design, you will have to learn how to alter your trace widths on boards. There are several different reasons that we have difference trace widths on boards. The specifications of traces for digital signals and power traces will be different. Therefore, we must change the widths of the traces on our boards. For more information about the importance of trace widths, you can read more here.

Altium Resource List

Quick-Start Tutorial from Altium

This video provides excellent resources for starting a project, creating a schematic, and selecting symbols from the manufacturers, similar to Cadence and their Ultra Library. They then made the PCB from that schematic. Lastly, they also showed how to create the Gerber Files and have the project ready to manufacture.

How are PCBs fabricated at ASU?

The following video shows our PCB manufacturing process.

Bypass capacitor basics

A bypass capacitor (aka “filter cap”) is a small capacitor that dampens electrical noise moving toward an IC. Electrical noise can cause circuit malfunctions. Unless otherwise specified in the data sheet of an IC, a 0.1 µF non-polarized ceramic capacitor usually makes a good bypass capacitor.

Cadence Forward Annotation Tutorial

Cadence Forward Annotation Tutorial

After having started working on a PCB layout, sooner or later you will likely find changes need to be made to your original schematic. Fortunately, you do not need to start the PCB design over as a result! Forward annotation allows you to essentially export changes made in your schematic into an existing layout, and here is how to do this in Cadence.
