To change local layout options for a particular layout, on the Layout menu, select Settings or Grid Settings to open the Tools > Options > General Options window to the Layout Editor tab. Local options for a layout may be changed only on the top level of the layout hierarchy, not from within a subcircuit.
Changes to global options only affect new layout designs . To configure options for existing designs, navigate to the Design Options window (i.e., from Layout, select Settings). Then choose options on the associated tabs, and click OK to save changes. All changes made in the Design Options window affect only the active design).
When the window is accessed via Grid Settings it opens on the Display area. When the window is accessed via Settings it opens on the Object area.
Saving global defaults is not undoable. When global defaults are saved, HFSS immediately writes them to the registry , then uses these new default values for all subsequent applications. The only way to revert to previous global values is to once again modify the default values , then do another global save.
The following buttons control changes made to the local layout options:
- Reset From Global Defaults is used to change the settings of all the tabs to those of the current Global settings. The reset affects only the window contents.
- Reset From Installed Defaults is used to change the settings of all the tabs to those of the initial-install defaults. The reset affects only the window contents.
- Save As Global Defaults saves the currents settings under all tabs to the Global defaults registry. This action is not undoable and is not scriptable. The save takes place immediately and does not close the window. Use of Cancel after Save As Global Defaults does not restore the registry.
- OK saves the settings of all the tabs to the current layout to be used locally, then closes the window. The action is undoable and is scriptable.
- Cancel closes the window without affecting the local settings of the layout.
Both the global and local Layout Options windows have six tabs. The options on each area are much the same for both global and local settings. The differences are:
- Save as Global Defaults is present only for each of the local options tabs.
- Always Show Layer Merging window on the Other area is present only for global options.
- Fit to Contents on the Display area is present only for local options.
- The Set based on page extent button on the Advanced area is present only for local options. This button calculates a distance tolerance based on the page extent.
