Identifying a problem early in the design cycle is always desired to avoid costly PCB re-spins.
Schematic audit is an integral part of the schematic creation process. It requires a lot of checks and balances for the designer to complete an error-free design. If any of these are missed, you might end up with problems like unconnected nets and power pins, property overlap, floating components, and so on.
Visual inspection of the schematic may not be efficient because it requires lot of effort and is error-prone.
There are different types of rule checks available in schematic tools like Graphical checks and Connectivity Checks. Of course, a few rules are specific to individual designs. However, we would like to know the commonly used DRC rules to ensure an error-free design.
We look forward to hearing from you.
