Allows you to specify a project-wide or individual timing assignment name. You can make individual timing assignments to pins and/or registers when you select Edit specific entity & node settings for in the By Node tab of the Assignment Organizer dialog box (Assignment menu). You can specify project-wide timing assignments when you select Edit project defaults & Compiler settings in the By Node tab of the Assignment Organizer dialog box. You can also specify project-wide timing assignments using the Timing Wizard (Assignments menu) or the Settings command (Assignments menu). You can view and edit the following types of project-wide and individual timing assignments with the Assignment Organizer dialog box:
