Quartus II Scripting Reference Manual © July 2013 Altera Corporation
These two Tcl commands reside in the ::quartus::project Tcl package. You must save assignment changes
before you run Quartus®II command-line executables. Note, however, that the Tcl commands
"execute_flow" and "execute_module" (part of the ::quartus::flow Tcl package) automatically call
"export_assignments" before they run command-line executables.
Example
## The following 3 examples remove project-wide,
## default parameter values

## parameter values
remove_all_parameters -name inst1 -to SIZE
