Description

Returns the size of a collection. Unlike a Tcl list, a collection is a container specific to the Quartus Prime software, whose elements can be accessed by using the "foreach_in_collection" command.

Example Usage
## Displays the number of global assignments
project_open chiptrip
set num_global_asgns [get_collection_size [get_all_global_assignments -name {*}]]
puts $num_global_asgns
project_close
Return Value Code Name Code String Return
TCL_OK 0 INFO: Operation successful
TCL_ERROR 1 ERROR: Collection does not exist with name: <string>. Specify the collection name returned by a Tcl command that supports foreach_in_collection. Note a valid collection name can become invalid if the variable holding the collection goes out of scope, as well as a result of some built-in TCL commands, for example 'string length'.
TCL_ERROR 1 ERROR: Nested calls to foreach_in_collection with the same collection name <string> are not allowed. Specify a different collection name for the other collection.
