Adding Connectivity
You can add (create) connectivity between blocks on a diagram using highways.
See Highways to create and use highways.
Note
When a highway is connected to a block, it is added as an “empty stack” of pins to provide a representation of the connectivity of the block. If you connect a highway to an empty stack and subsequently delete the highway, the stack is also deleted. You can hide the Stacked Pins decoration through styling if required. See also Stacked Pins.
Procedure
Press the space bar and enter Highway.
Position the cursor over the point on the block to place the first end of the new highway.
Click and drag to define highway segments.
Double‑click the destination block or highway to complete the connection.
Results
If the highway is not attached to an existing highway, a new highway is added to the Design Browser.
If the new highways segments are attached to an existing highway, they become part of the existing highway. No new highway is created. Note To view the conductors in the highway: right-click the highway and select View Usage, or press the space bar and enter View Usage. See Viewing the Connectivity that Terminates at Blocks.
Tip See Conductors to add connectivity between blocks.
