Interlayer spacing constraint DRC (detect soldermask layer & silkscreen layer conflict)

ichliebedich over 3 years ago

Hi All

There are two layers Silkscreen_Top and Soldermask_Top below

and if conflict happen both of them like below, How can I create DRC error mark?

currently I created the interlayer spacing rule for them like below

and set the gap with value, but when I refresh the DRC error mark command, there is no any DRC error happened...

How can I make the DRC error at the conflict point between that two layer with interlayer Constraint Rule?

The InterLayer DRC Checks are not intended for these type of checks. The Silkscreen is only available in this screenshot because it has been added as a layer in the cross section but that doesn't mean you can define a DRC to it. The screenshot below came from some notes about what the Interlayer checks are there for.

If you have either an Allegro Venture or Allegro Enterprise license you can DRC between Silkscreen and Masks using the Manufacturing - Design for Manufacture - Silkscreen checks.

You can achieve this with the help of Ravel rules which is available in the 'Manufacture -> setup Ravel Rules in CM' menu.
