22.214.171.124. Entity-bound Constraint Scope
|Constraint Scope Type||Constraints Apply||To Enable Instance-bound Scoping|
|Automatic||To all instances of the assigned entity throughout the project, except for top-level ports (get_ports) and clock names (get_clocks).||Default mode for SDC_ENTITY_FILE. No additional steps required.|
|Manual||To the current instance of the assigned entity, except for top-level ports and clock names, which have a global scope.
Collection filters also have global scope, unless you prepend them with get_current_instance, which sets the instance scope.
|Prepend the collection filter with get_current_instance.|
The following example constraint shows use of get_current_instance to return the hierarchical path to the current entity for manual constraint scoping:
set_false_path –from [get_registers "reg_a"] –to \ [get_pins “[get_current_instance]|*reset”]
