PERIOD. ~ ~ ~ Rule 274: No "ifs", "ands", or "buts" about any of the preceding 273 Rules. PERIOD. Rule 275: Never think that these Rules do not apply to you. PERIOD. Rule 276: Never forget these Rules. PERIOD. PERIOD The other 271 Rules - Don't even ask - If you have been in the industry for several years now and still don't know them by now, you are in deep yogurt and nothing will help you - If you are new to the industry, you will learn them in due time - Patience. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: "Protel EDA Forum" <[EMAIL PROTECTED]> Sent: Wednesday, November 27, 2002 6:36 PM 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.
