Hi yogi,
The error "Cannot resolve Simulink signal object for output port" typically occurs when Simulink is unable to find or properly configure a signal object that is expected to be associated with an output port. This can happen for various reasons, such as incorrect signal object definitions, missing signal objects, or issues with the configuration of the signal object in the model.
You can try to first not resolve the output port to any Signal objects and note the signal properties from the Properties dialog box of the Signal. You should also note the Signal Attributes values for the port by going to the Block properties dialog box for the connected block. After this, make sure that the Signal object is set the properties accordingly as noted. Then try to resolve the signal to an object.
