Specifying Symbol Generator Pin Sorting

Note: Pin sorting is valid only when you create a symbol from a schematic.

When the system creates symbols automatically, TSG sorts the pins either alphanumerically by pin name (default) or geometrically according to the pin’s relative position in the source schematic view.

To specify how TSG sorts the pins, do the following:

1.Choose Design – Options – Editor.

The Editor Options form appears.

2.In the Command Controls section of the form, set the Symbol Generator Pin Sorting option to alphanumeric or geometric.

3.Click OK.

Automatic symbol generation now uses the specified pin sorting method.

You can change the default (alphanumeric to geometric) by editing the ssgSortPins environment variable. The system uses this variable when you choose

Design – Options – Save Defaults. It is also available as arguments to the schGetEnv and schSetEnv procedural interface SKILL functions.
