Changing DRC ( Spacing Constraint) rules in allegro.

RFStuff
RFStuff over 12 years ago

 Dear All,

I am using Allegro 16.2 tool for my PCB layout.

Earlier I designed my PCB layout in Board not in Board Wizard.

My DRC check is showing error when the trace spacing is lesser than 5mil.

But now, I want to change this DRC rule ( Spacing Constraint) i.e. the  Minimum Line to Line spacing to 10 mil.

How I can do this .

Also I need to change the constraint for Shape to Shape spacing.

Could anybody please tell how it can be done .

 

Kind Regards

     All constraints are managed through the constrait editor.  There is normally an icon to get you there but otherwise it's Setup->Constraints->Spacing


    Dig into the other constraint menus as well.  Constraint editor is a little cumbersome at first but then makes sense.  It's used for spacing, electrical, matching, and relational constraints.
