About View Level Functions

Adhil,

The functions (which correspond to the  View->Area Display menu in VLS) allow you to alter the start and stop display level for an area of the design, rather than being applied to the entire design (as set via the Options->Display form). This you can keep everything at level 0 (just instance boxes), but show full depth (or whatever for one or more regions of the layout).

The reason why it failed was quite clearly described in the error message - you gave it a cellView ID, but it is expecting a window ID. So you'd need to pass something like the result of hiGetCurrentWindow() to the function instead. Unless you've set an area, it will return nil (but you could always use the geSetAreaViewLevel function).

There's also the ge.*InstViewLevel functions which allow the view level to be on specific instances. There's no UI for this (for some reason), but I wrote this SKILL function many years ago to allow me to easily toggle the view depth on selected instances:

Function to toggle the Inst View level on selected objects
between 0 and 20.

abSetInvSelInstView() will set the depth on everything except
the selected instances.

abDeleteInstView() will delete all selected instance views.
