Name Description
[-class] Object type to query for properties. Ignored if object is specified.

[-verbose] Suspend message limits during command execution
[<object>] Object to query for properties
[<pattern>] Pattern to match properties against Default: *


Gets a list of all properties on a specified object or class.
Note: report_property also returns a list of properties on an object or class of objects, but also reports the property type and property value.


-class <arg> - (Optional) Return the properties of the specified class instead of a specific object. The class argument is case sensitive, and most class names are lower case.
Note: -class cannot be used together with an <object>.
-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.
<object> - (Optional) A single object on which to report properties.
Note: If you specify multiple objects you will get an error.
<pattern> - (Optional) Match the available properties on the <object> or -class against the specified search pattern. The <pattern> applies to the property name, and only properties matching the specified pattern will be reported. The default pattern is the wildcard '*' which returns a list of all properties on the specified object.
Note: The search pattern is case sensitive, and most properties are UPPER case.


The following example returns all properties of the specified CELL object:
list_property [get_cells cpuEngine]
The following example returns the properties matching the specified search pattern from the BEL class of objects:
list_property -class bel *NUM*
