I have defined an Anti Pad for the differential pairs of a high speed connector within the padstack for those pins. I have checked the box beside "Enable Antipads as Route Keepouts (ARK)" on the parameters tab of the padstack.
Is there anything else I need to enable within Allegro (16.5) to get this to work? When I place the connector on my PCB I am not seeing the Antipad Keepouts.
Is this feature only used for the SPECCTRA autorouter?
Thanks in advance for the help!
I created a padstack as follows...""Suppress unconnect int. pads: legacy artwork" and "Mech pins use antipads as Route Keepout" boxes checked. Hole type...Circle Drill. Plating...Non-Plated, Drill diameter 50.0. Layers tabs...begin, default internal, end layers all Regular Pad...Circle...40.0 (to avoid copper shavings) and all the Anti Pads...Circle...50.0. Thermal Relief pads...Null. I then add this padstack as a mechanical pin on a part. In the library or on the board I do not see any route keepouts and I can route a trace directly over the hole and do not get an error. Can anyone let me know what I am missing in order to get this option to work?
