Forgive me if you already know this: If any buss connects to a port make sure the busses have net labels.
For example an 8 way buss with lines D0 to D7 connected to a port needs a net label "[D0..D7]" without the quotes placed on it for connectivity also the port must have the same name (that is [D0..D7]). See Schematic Help topic "Bus (Schematic electrical design object)" There is also an example on p99 of the manual. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] > Sent: Thursday, 28 November 2002 13:37 > To: Protel EDA Forum > Subject: [PEDA] Connectivity Nightmares > > > Hi all: > > I usually use a hierarchical structure for my schematic > documents, with a > main document with all the connectors on it, then below that a block > diagram, and then the actual circuitry on one or more levels > below that. > > I'm currently doing a reasonable-sized board, with lots of > digital lines, > and have amalgamated those lines into busses for the most > part, however when > I try to synchronise my PCB, I get lots of errors due to the > net labels I've > chosen not being mapped across separate sheets.
