Tcl Package and Version

Belongs to ::quartus::project

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 matching. 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 AUTO_INSERT_SLD_NODE_ENTITY 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.
