Tcl Package and Version

Belongs to ::quartus::project 6.0

Syntax remove_all_global_assignments [-h | -help] [-long_help] [-entity <entity_name> ] [-fall] -name <name> [-rise] [-section_id <section id> ] [-tag <data> ]
Arguments -h | -help Short help
-long_help Long help with examples and possible return values
-entity <entity_name> Entity to which assignment belongs
-fall Option applies to falling edge
-name <name> Assignment name (string pattern is matched using Tcl string matching)
-rise Option applies to rising edge
-section_id <section id> Section id
-tag <data> Option to tag data to this assignment
Removes all matching global assignments.

The "-name" option is not case sensitive. This option can take 
string patterns containing special characters from the set 
"*?\[]" as the value. The value is matched using Tcl string 

This Tcl command reads the global assignments found in
the Quartus Prime Settings File (.qsf). This Tcl command filters
the assignments data found in the .qsf and removes the data
based on the values specified by the "-name" option.

Certain sections in the .qsf can appear more than once. 
For example, because there may be more than one clock 
used in a project, there may be more than one CLOCK section 
each containing its own set of clock assignments. To uniquely 
identify sections of this type, a <Section Id> is used. 
<Section Id> can be one of three types. It can be the same as 
the revision name, or it can be some unique name. The 
following is a list of sections requiring a <Section Id> and 
the associated <Section Id> description:

Section Id                    Description
---------------------------   ------------------------------
CHIP                          Same as revision name
LOGICLOCK_REGION              A unique name
EDA_TOOL_SETTINGS             A unique name
CLIQUE                        A unique name
BREAKPOINT                    A unique name
CLOCK                         A unique name

For entity-specific assignments, use the "-entity" option to 
remove the assignment(s) from the specified entity. If the
"-entity" option is not specified, the value for the 
FOCUS_ENTITY_NAME assignment is used. If the FOCUS_ENTITY_NAME
value is not found, the revision name is used.

Assignments removed by using this Tcl command are 
not saved to the Quartus Prime Settings File (.qsf) unless you
explicitly call one of the following two Tcl commands:

1) export_assignments
2) project_close (unless "-dont_export_assignments" is specified)

These two Tcl commands reside in the ::quartus::project Tcl 
package. You must save assignment changes before you run 
Quartus Prime 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.
