Description
Sets the type property for routes and terms on power or ground nets only. Other objects, such as nets in the set, are ignored. If no valid objects are found in the set, the command fails.
This command is used to ensure that power structure objects are correctly labeled. Space-based Router and Chip Optimizer uses a heuristic to guess what these objects are, especially when they are created externally. An incorrect guess can prevent the object from being properly connected. For example, a tap pin in one design, that should be connected pin-to-trunk, was incorrectly labeled as a tie-off, so the power router did not connect to it. With this command, the pin can be identified as a tap without modifying the OpenAccess database.
Arguments
