Eliminate Mistakes in Your Schematics with Electronic Rule Checking
In times of rising design complexity and shortened timelines, it’s more and more for mistakes to sneak through in the schematic that can translate to the printed circuit board. Read on to find out how to easily identify and eliminate issues in your schematic with the Electronic Rule Checking your PCB in Altium Designer®.
Many designers and companies put all their efforts in having a proper PCB layout and, nowadays, checking in real time the surrounding mechanical conditions. But what if the schematic already contains errors? Usually, there is a human driven review of the PCB layout but in times of rising design complexity and shortened timelines, it’s more and more for mistakes to sneak through. What can be done to ensure that no errors in the schematic interrupt your workflow moving forward?
Using Electronic Rules to Identify and Correct Issues Early in Your Designs
The electronic rule check (ERC) function in professional PCB design software can help you in finding and eliminating mistakes in the schematic by checking some basic rules and the ‘grammar’ underlying the design. By configuring the rules to perform checks that are specific to your design rule, ERC identifies problems so you can correct them early in the PCB layout. Plus, setting up and running ERC checks takes very little time...actually a fraction of the time you might spend manually checking the design. This lets you spend your time designing, not re-checking work.
One way to use ERC is to split up the preferences for this check in two general regions that cover the general ‘grammar’ of schematic design and a connection matrix defining which elements are allowed to be connected in which way, as shown below.
The ‘grammar’ area covers different settings regarding the usage of busses, components, documents, harnesses, nets, parameters etc.
Altium Designer can support this way of working with a wide range of configurable check routines that can be used either to check the schematic after it has been created or by using the online ERC and batch checks when creating your production data.
