Answers Database 2.1i: Constraints Editor - Only first of several similar constraints placed in the editable constraints window Record #6385 Product Family: Software Product Line: M1 Implementation Product Part: Constraints Editor Product Version: 2.1i Problem Title: 2.1i: Constraints Editor - Only first of several similar constraints placed in the editable constraints window Problem Description: Urgency: Standard General Description: If the UCF file contains the following constraints, only the first one is placed in the editable constraints window. The other two are placed in the read-only constraints window. INST "TST/LVL/REQ/REQ1" LOC = "CLB_R14C48.S0"; INST "TST/LVL/REQ/REQ3" LOC = "CLB_R14C48.S0"; INST "TST/LVL/REQ/IREQ_I-" LOC = "CLB_R14C48.S0"; Solution 1: To edit constraints that do not show up in the editable window, manually edit the ucf file and run it through the Constraints Editor or through the implementation flow. This will be fixed in a future release of the software. End of Record #6385 - Last Modified: 06/28/99 09:43
