Changing the Parameters of a Template-Derived Master

One can change all of the instances that use a particular parameter set to a new parameter set by changing the master cell of the instances. The original template cell must be accessible, as for changing individual instances. The procedure is as follows.

  1. Make the master cell the current cell. The easiest way to do this is to select an instance of the master cell (one of the instances to be changed) in a drawing window, and use the Push command in the Edit Menu. The master can also be selected for editing from the Cells Listing pop-up, or by giving its name in the Edit command.

  2. Press the Cell Properties button in the Edit menu. This brings up the Cell Property Editor, which will list the properties of the current cell (the master derived from a template).

  3. In the listing, there should be an entry for property number 7198 named ``Tmpl Params''. If not, the current cell is not a master derived from a template, or the template has no parameters.

  4. Select the Tmpl Params property, and press the Edit button in the Cell Property Editor.

  5. The current parameter string will appear on the prompt line, where it can be edited by the user. Edit the string to supply the new parameters.

  6. Press Enter when the modifications are complete. This will rebuild the master from the new parameter set. All instances of this master will contain the new master's geometry.
