[PCB_FORUM] Re: NO_RAT property appearing from schematic

Hi All!

 

Is there a rule of thumb for the distance from a diff pair to the next diff
pair? I heard that you should have twice the distance of the overall width
or the preceding diff pair.

 

Thanks

Was the property added in Allegro?

Subject: [PCB_FORUM] NO_RAT property appearing from schematic

I am reading in a netlist from Concept which is suppose to have no
constraints or properties. However, I am getting a NO_RAT property on the
GND net. Doing a search on the ascii files of the schematic pages shows no
instances of this property. The property does not appear in any of the dat
files created from Concept. Any ideas where this property is coming from?

 

Thanks for any ideas
