I accept a passive pin driving an input in the rule matrix. It happens all the time - series termination resistors cause it, connector pins cause it - it's a normal part of a design, and doesn't merit a warning, let alone an error. (However, I do not accept, under any circumstances, an unconnected pin. That's a warning, cleared if necessary with a No-ERC) Steve * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/[EMAIL PROTECTED] * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
