Layout

The Layout pop-up menu is context specific and shows only options for the active command.

Finish Routing finishes the routing connections from the last digitized points. If the routing area is obstructed, the command is terminated.

Route As many As Possible while bus routing, the Finish Routing command will try to complete as many connections as the available routing area permits.

Route Only If All Succeed while bus routing, the Finish Routing command must complete all paths successfully or none are routed.

Turn gather bus wires on/off changes the cursor to a single bus cursor and wires are spaced by the amount specified in theSpacing for Gather Bus Wires settings.

Add Via opens the Add Via form, and all available vias and routing layers that can be reached from the current routing layer are displayed for selection. Buttons for inaccessible layers are grayed out.

Via Pattern opens the Via Pattern form. When routing multiple paths, multiple vias are added according to a via pattern that you choose.

Pick up dropped wires restarts bus routing at a new location after some paths have been dropped. Guides appear from the new starting points and back to the dropped paths. The dropped paths can then be routed from the new location. After routing the paths from the new location, you can route the dropped paths individually from the location where it was dropped to the location where the paths were restarted.

Set up opens the Route Options form, which sets the routing controls for two categories;

General and Bus.

Width

Match Pin Width sets the net width to the width of the pin you are editing.

Narrow sets the width of the active segment to match the shortest side of the pin to which the path is attached.

Wide sets the width of the active path segment to match the longest side of the pin to which the path is attached.

Match Path Width sets the net width to the width of the net you are editing.

Specify opens the Create Path form, which lets you specify a new width for the path.

Turn checking off/on prevents routing rule violations between routing objects, such as paths, vias, and pins.

Reports Form

General

Route Status creates a report that includes information about unconnects, conflicts, rule violations, number of pins, number of components, vias, and length information for each routing layer.

Network creates a report about all nets in the design. You can sort the net information by the length of the layers or select the Total Lengths Boolean to further sort them.

Length By Layer displays the report in a new window with the nets sorted by the length of the layers.

Total Lengths - Sort By

Name sorts the information about the nets alphabetically according to the net name.

Ratio sorts the information from the highest to the lowest ratio of the actual routed length divided by the manhattan length.

Length sorts the information from the highest to lowest length rule.

Extra sorts the information from the highest to the lowest difference between the actual routed length and the manhattan distance.

Component displays a list of components placed in the current design. The report includes component placement information, nets, and pins associated with the component and component pin positions.

Net displays a list of nets for the current design. The report includes rules applied to the specified net, connections, coordinates, components, component pins, layers, and vias.

Rules displays a report that contains information about routing rules applied to the current design. You can specify to view All rules associated with the current design or Specify which rules will be displayed in the report.
