2.7.5. Filtering in the Schematic View
You can filter a netlist by selecting hierarchy boxes, nodes, ports of a node, or states in a state machine that are part of the path you want to see. The following filter commands are available:
- Sources—displays the sources of the selection.
- Destinations—displays the destinations of the selection.
- Sources & Destinations—displays the sources and destinations of the selection.
- Selected Nodes—displays only the selected nodes.
- Between Selected Nodes—displays nodes and connections in the path between the selected nodes.
- Bus Index—Displays the sources or destinations for one or more indexes of an output or input bus port.
- Filtering Options—Displays the Filtering Options dialog box:
- Stop filtering at register—Turning on this option directs the Netlist Viewer to filter out to the nearest register boundary.
- Filter across hierarchies—Turning on this option directs the Netlist Viewer to filter across hierarchies.
- Maximum number of hierarchy levels—Sets the maximum number of hierarchy levels that the schematic view can display.
To filter a netlist, select a hierarchy box, node, port, net, or state node, right-click in the window, point to Filter and click the appropriate filter command. The Netlist Viewer generates a new page showing the netlist that remains after filtering.
When filtering in a state diagram in the State Machine Viewer, sources and destinations refer to the previous and next transition states or paths between transition states in the state diagram. The transition table and encoding table also reflect the filtering.
