Looking for opinions on this and to see how others are doing these. Our CAD group has gotten into discussions as to whether or not we should be doing solid power/ground planes as positives. As a long time Allegro user I've been accustomed to doing solid planes as negatives and static, though lately Ive been making these planes negative/dynamic to take advantage of voiding of route keepouts on certain layers. So could I find out if anyone is going with databases that are all positives as far as layers are concerned? And any comments Pro or Con as to using this method. thanks, Mike Gnieski EMC2 Corporation 176 South Street Hopkinton, MA 01748 ----------------------------------------------------------- To subscribe/unsubscribe: Send a message to icu-pcb-forum-request@xxxxxxxxxxxxx with a subject of subscribe or unsubscribe To view the archives of this list go to //www.freelists.org/archives/icu-pcb-forum/ Problems or Questions: Send an email to icu-pcb-forum-admins@xxxxxxxxxxxxx -----------------------------------------------------------
