Environment variable: dimmingOn

Scope

• none: Does not apply dimming. This is the default. Even if you change the Dim Intensity from zero percent to one hundred percent, the objects remain undimmed. The only exception is that the background cellview dims if its Display field is set to dimmed.
• outside: Dims everything but the instance, figure group, or any object you are editing in place. The dimmed objects represent the objects that are non-editable at the current edit level. With the outside setting on,
  • If a Pcell exists at the edit level and is visible at the edit level, its contents are not dimmed. For example, in the following hierarchy, both PcellA and PcellB are be visible at Display Stop Level 32. However, at the Top edit level when the dimming scope is outside, the contents of PcellA are undimmed and those of PcellB are dimmed.
    
    
  • If the Via Shapes option is on, vias belonging to the edit level are not dimmed.
  • If the Instance Pins option is on, instance pins belonging to edit level-1 are not dimmed.

• all: Dims the design completely as soon as you select this option. If you select an object and Dim Intensity is set to hundred percent, only the selection box is displayed.
• eipSurround: Dims all the objects surrounding the EIP hierarchy.
