Batch and Online DRC have difference

Question asked by fuji on Jan 26, 2020

Hello dears,

 

We started to use Package Clearance Type Rules. But it seems that Batch and Online DRC have difference. Online DRC doesn't detect the error, but Batch DRC detects it. Therefore we can place the parts, but realize the error after run Batch DRC.

 

It looks like Batch DRC checks "Package to All Packages", but Online DRC checks "Package to Package Clearance".

Is this a correct working? How should we set the clearance values?

 

We would like to set bigger value to "Package to All Packages" than "Package to Package Clearance". Because chip parts to chip parts clearance can be narrowed, but chip parts to others(IC and so on) clearance can not.
