Electronic – Are there op amps in Logicworks

I figured this one out. It turns out you have to create your own bus port inputs and outputs. It's fairly easy:

Open a new file for creating a device symbol. In Device Symbol Editor, Choose “Set to primitive type” in Options-> subcircuit/part type and then choose Port Connector. The symbol will then be of Type Port Connector. Create a number of pins for a bus by choosing Option->Add pins with, for example, INPUT[A0..A3] for a four-bit input bus that has signals A0 to A3. The signal names must match those that the bus is to be connected to. Therefore each bus port connector can only be used once to connect signals with same names. A bus internal pin can be either output or input or bi-directional. Set pins on a bus to be output pins if the pins are to be connected to inputs of a sub-circuit. Draw a bus symbol that can be any shape you want. Select a bus pin from the symbol palette and place it on the bus symbol. There are four bus pins, one for each side of the bus symbol. A screen capture on the right shows how a 4-bit input bus port can be created. Notice that the pin functions are designated as Output, although the bus port is an input bus port. Make sure the pin directions and the number of pins match the intended application. Save the port connector symbol to your own library.

You probably want to use a bus. A bus combines multiple wires into one larger 'wire' / array. See this question for adding buses to a custom part.
