15.15.1.3 Filter Unassigned Instances

To display a subset of the unassigned instances, you can create and apply filters.

• To filter the list box by a pattern, select Matching pattern, enter the string to match, and then click Filter. For example, enter *U18* to display only unassigned instances containing the characters U18.
• To filter by a net name, select Connected to nets matching pattern, enter the name of the net to match, and then click Filter. The Unassigned instances list will display only macros assigned to the net name you specified. For example, enter add_count_clk to display only macros assigned to the net named add_count_clk.
• To filter by a port name, select Connected to ports matching pattern, enter the name of the port to match, and then click Filter. The Unassigned instances list will display only macros assigned to the port name you specified.
• Filters are valid for both regular and Block flows. Note that in regular flows, each port is connected to only one instance, which is an I/O.
