defining region

Solution

You can setup constraint region around this component and avoid these DRCs.

Open constraint manager and create a Spacing Constraint set (CSet) for the constraint region.

1. Open Constraint Manager

2. Select the Spacing Domain, All Layers worksheet

3. Right mouse button (RMB) on the Objects and select Create Spacing CSet

4. Type the name of Spacing CSet and change the pin to pin constraints that allow pin to pin spacing for the 'special' component.

Create a region and assign a spacing CSet to the region.

1. In Constraint Manager, select Region > All Layers

2. RMB > Create Region

3. Give a name to the region, and select OK

4. On the Region worksheet, select the region that you just created, and assign the Spacing CSet that you had created in the previous step. The rules of the spacing CSet are automatically inherited by the Region.

Create a shape on the Constraint Area subclass and assign the region rules to it.

1. On Allegro PCB Editor, select Shape > Polygon or Rectangular.

2. In the Options panel on the right hand side, select a Class/Subclass of Constraint Region/All.

3. From the drop down in the Options panel, select the region you had defined in the previous step.

4. Draw the rectangle or polygon around the component.

One thing to note:  If you are just trying to avoid Pin to Pin DRCs on the same component you can add the Symbol Property "NODRC_SYM_SAME_PIN" to the symbol definition which will disable the Pin to Pin checks within the same symbol.  Now if you are trying to avoid Trace to Trace (Line to Line) DRCs when connecting to the pins then you will be forced to add a region as specified above.
