Get used to the synchronizer, it is the way of the future. Netlist load is a remnant of the old batch processing days.

Re: [PEDA] TO3 footprint
I fixed the TO3 by assigning only one pad as pin 3. Will multiple pins with one pin number work? I have not had a problem with Netlist Load as I force it to browse for the Netlist File not using the netlist it shows. The same bug is in AutoCAD 2000 for inserting a block ...the block does not get updated unless you force it to browse for the file. I think its a Windows type of bug. Am I wrong about this? I will try to remember to use the Update PCB. Must I make sure the Rooms crap is turned off??

Do I have to use a >schematic and footprint pin 3A and pin 3B? Let me guess. Mr Adolphs used Netlist Load instead of the synchronizer (Schematic/Design/Update PCB). There is a known bug in the Netlist Load routines which causes assignment oscillation: the existing assigment will change state between the correct net name and no-net with each successive load. The easiest fix is to use Update PCB, but if that is not available, as with a net list from another CAD Schematic program, making a fresh load after having cleared out nets will produce correct assignments. The command Design/Netlist Manager/Menu/Update Free primitives... will restore the free primitive assignments (i.e., track and via). Note that non-pad primitives that are part of footprints are also updated in addition to free primitives. A symptom of the problem is that each netlist load produces new macros, even though the same netlist was just loaded already. The macros oscillate the assignments. It is a good practice to reload the net list or resynchronize before beginning routing and after completing a design; if the only macros that are created are the oscillating kind, or no macros are created, the load can be cancelled. It would still be prudent to manually verify those pads. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 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 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
