What is DRC in Altium?
Ensuring Design Integrity with Design Rule Checking (DRC) in Altium Designer.
What is DRC in PCB design?
What is design rule check (DRC) in PCB design? A design rule check is a set of rules used by a designer to ensure the schematic matches all manufacturing considerations and dimensional tolerances set for a board. Production processes have a margin of error for the variation in the products that are manufactured.
How do I waive DRC in Altium?
DRC violations can be waived by:
- Right-clicking on a one or more violations selected in the Messages panel.
- Right-clicking on one or more violations selected in the Violations region of the PCB Rules and Violations panel.
- Enabling the Waive this violation checkbox in the Violations Details dialog.
How do I fix my DRC violation?
To fix this type of spacing violation, the net needs to be placed away from the via, or different size vias need to be inserted so it will meet the same net spacing requirement. In above case, routing taken in reverse U shape will meet the spacing requirements as below.
How do I get to the DRC in Altium?
A batch-mode DRC is initiated by clicking the Run Design Rule Check button, at the bottom-left of the dialog. After the check has completed, all violations are listed as messages in the Messages panel.
What is solder mask sliver?
Minimum “Solder Mask Sliver” means the pip of Soldermask between the pads. In our specifications we declared the thickness with a minimum of 0.1 mm. In example for PCB-POOL orders: The applied solder pad is increased 0.075 mm around the copperpad. The remaining land between the pads must be at least a width of 0.1 mm.
What is DRC layout design?
Design Rule Checking (DRC) verifies as to whether a specific design meets the constraints imposed by the process technology to be used for its manufacturing. DRC checking is an essential part of the physical design flow and ensures the design meets manufacturing requirements and will not result in a chip failure.
What is DRC and LVS?
SmartDRC/LVS performs physical verification of analog, digital and mixed-signal ICs including design rule checks (DRC), layout connectivity extraction and layout vs schematic (LVS) comparisons.
How do I waive a violation in Altium?
Access
- From the PCB Rules and Violations panel, right-click on a selected violation(s) then select Waive Select Violations from the context menu.
- From the Messages panel, right-click on a selected violation(s) then select Waive Violations from the context menu.
What are DRC errors?
DRC error type If two different net objects too close, and the distance less than the Design Rule clearance, it will show the Clrearance error.
What is silk to solder mask clearance?
Summary. This rule checks the clearance between any silkscreen primitive and any solder mask primitive or exposed copper-layer primitive (exposed through openings in the solder mask). The check ensures that the distance is equal to or greater than the value specified in the constraint.
What is waive DRC violation in Altium Designer?
Rather than creating a custom rule, Altium Designer includes a Waive DRC Violation feature, that allows the designer to selectively waive any DRC violation. definition: Waive – refrain from demanding compliance with (a rule or fee ).

Do I need a batch DRC or online DRC?
So while good designers know the value of the Online DRC, they also know that board design should begin and end with a Batch DRC. The dialog is accessed from the PCB Editor by clicking Tools » Design Rule Check from the main menus.
