Hierarchical Color Locking Check

As mentioned in Color Locking section, there are two types of color locks that can be assigned to a shape: the color state (dbLock) and hierarchical color locks (HCL).

While a shape can have only one dbLock, it could potentially have multiple HCLs applied from various levels of the hierarchy. A color conflict exists when there are multiple locked color assignments for a shape.

To check for potential color conflicts related to color locking:

1. Choose Hierarchical Color Locking Check from the Checks drop-down list.
   The number of conflicting coloring locks is reported in the CIW. Annotation markers will appear in the canvas where the conflicts were found.
2. Choose Window – Assistants – Annotation Browser to open the Annotation Browser and inspect the conflicts listed on the Misc tab in the MPT grouping.
   
   
   Potential conflicts include:
   • HCL in hierarchy over HCL in hierarchy
     There are hierarchical color locks of different/same colors at different levels of the hierarchy for a shape.
   • HCL over dbLock shape in hierarchy
     There is a hierarchical color lock on a shape that is also locked in the cell master.
   • HCL over shape in locked via
     There is a hierarchical color lock on a shape that is part of a locked or partially locked via.
3. Resolve conflicts by Removing Color from Shapes.
