Hi I have had a few discussions previously on this list about the connectivity models within 99SE and how I have had in some cases seen errors where power ports are not treated as global when using Sheet Symbols/Port connections.
Before committing the last of my larger designs to 2004 I would like to track down the error of my ways. Some screenshots here http://www.proteluser.com/bbs/showthread.php?p=68#post68 A short summary is that the design has one parent sheet and the rest are child sheets. No complex hierarchy. Connectivity model is set to sheet Symbol / Port connections as it should be. This is a real design in production, not a test board. But Update PCB fails with errors. If previewed it wants to rip up the power nets completely. If I generate a netlist and then try to load it manually I get a similar issue but with more detail, this time the power nets are ripped up and I get netlist load errors 'net already exists' as it tries to add many instances of the same power net name (one instance per sheet). If I add a sheet entry to each sheet symbol with the name of the power net and as a sheet port to the child sheets all is happy, no errors. My understanding was always that power ports were always global, but I seem to have an exception here, unless I cannot see the wood for the trees. Any suggestions appreciated. Best Regards John A.
