Design Rule Checking (DRC)

CR-8000 Circuit Adviser

Design Gateway’s Circuit Adviser enables engineers to conduct concurrent, advanced electrical rule checks during logical circuit creation. Users can specify rules and conditions, create check results, cross-probe results with the design and generate summary reports.

Checks include:

Power and ground supply polarity
Net voltage polarity
Input pin voltage
"Must connect" pins
Pull-up/pull-down resistors
Component voltage ratings
Component power dissipation ratings
Maximum Repetitive Reverse Voltage check (VRRM)
Component pin input/output current balancing
Worst-case analysis for voltage/power ratings
Diode forward voltage/power ratings
Component pin capacitance

Circuit Adviser rule checks can be further enhanced, utilizing the annotation of operating point voltages annotated to the circuit design from analog simulation.

EMC = DRC²: The Importance of EMC Rule Checking

When it comes design rule checks for PCB designs, there are checks that should be performed that are just as important as spacing rules. Strict adherence to basic PCB design rule checks, such as track to track, track to via, via to via, pad to track etc. – though necessary to avoid short circuits – only scratch the surface when trying to identify potential design flaws. I often see PCB designs that are completed based on this premise and wonder what else could be hiding in the design?
