M1.5: NET PERIOD constraints are incorrectly interpreted by the Constraint Editor

説明

General Description: If a .ngd or .ucf file contain a period constraint written

using the following syntax they are not picked up by the Constraint Editor.

NET CLK PERIOD = 30 ns;

NET "CLK" TNM_NET = "CLK"

TIMESPEC "CLK" = PERIOD "CLK" 30 ns;

This syntax will be picked up by the Constraint Editor.
