Hi,I am trying autoroute the first time and pretty new to Allegro. The cline generated by autoroute are all touching the antipad. Is there a simple way to adjust, say, the line have to be at least 8 mil away from the antipad or in some case, mid point between two antipad?I know that it is possible to set constrain area and defind them at individual area but are there a more general setting? Using 15.1.Thanks.
Hi, There is no setting for cline to antipad. clearances are copper to copper. You can try to adjust your cline to pad clearance or reduce the size of the antipad. I would check with my fab house before just reducing the size. There is a setting in the gloss commands in the autorouter to center lines. In version 16.0 Allegro XL there is a check for trace over void which checks for this type of thing. Unless this is a high speed impedance controlled board some trace over hang shouldn't be a problem. Here is another post on this same subject. http://www.cdnusers.org/Forums/tabid/52/forumid/5/postid/8004/view/topic/Default.aspxRegards,BillZ EMA Design Automation
