Re: [PEDA] Connecting Power
I'm sure if this question has been asked before, but here's my suggestion: Check the library symbol of your part for - which end of the pin is the connectivity end - proper placement of the connectivity end on a grid point Or even better, redraw the symbol without any hidden pins. Eventually even a separate power part in a multipart component. Good luck, Emanuel SHAWN wrote: I'm sure this question has been asked before, but here it is again: In some cases I'm unable to connect power to a chip. For example, I'm trying to power the hidden VS power-type pin of a LMD18200T(11) chip with +38V. If I unhide the pin, it won't connect to a wire, and if I connect a VS port to a +38V port that, or course, gives a 2-ports-on-the-same-net error.

Re: [PEDA] Connecting Power
Forget those built in libraries. They are though for demo purposes. Draw your own.

Check the schematic symbol carefully to see that the pin ends on a grid point, and is placed right-way-around. -- Peter Bennett TRIUMF 4004 Wesbrook Mall, Vancouver, BC, Canada GPS and NMEA info and programs: http://vancouver-webpages.com/peter/index.html * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 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/proteledaforum@techservinc.com * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

I remember learning the workaround in college, but can't remember what that workaround was. You know the technique (it's not a workaround because it is the intended way hidden pins work). Unhide the pin and wire to it. Now, why you are not able to wire to it is another story. Perhaps the tip of the pin is off-grid? What else is in the net, and is this a ports and sheet-entry connections type of schematic? If you wire to the pin instead of hiding it, no global net is created. However, if you use a power object for +38V, this will create a global power net.
