4.7 Debugging techniques

After a bus port is connected to pins in a

subcircuit, right click on the bus symbol to

open Device Info window. Check each pin

of the bus to see if their types are correct.

For example, all the pins of an output bus

port should have pin type of Output.

Once a device symbols is corrected. Get a

copy of it in a schematic window. Right click on a bus pin of the device symbol to open Bus Pin

Info window. Choose a pin and click Pin Info to find out if the pin is of correct type. If it does not

have the correct type, edit the device symbol to check if the pin type is defined correctly.

4.8 Modifying a bus port in a subcircuit

After modifying a bus port in a subcircuit, the subcircuit needs to be detached and reattached to

the device symbol.

A subcircuit can be detached with Schematic->detach subcircuit at either device symbol level or

subcircuit level.

A device symbol can get a new subcircuit by selecting it and then choosing Schematic->attach

subcircuit.
