Simulink is the common environment, so you can use Simulink signals to connect between SimRF and SimPowerSystems.
To get a Simulink signal from SimRF, use a SimRF Output. To drive a SimRF component with a Simulink signal, use the SimRF Inport to convert the data signal into a SimRF signal.
Converting Simulink signals to electrical connections or vice versa requires using a SimPowerSystems block that features both Simulink ports and electrical terminal ports. Some SimPowerSystems blocks feature only one type of port. You can make measurements using components from the Measurements Library. Check out the Current Measurement, Voltage Measurement, and the Multimeter. These all output Simulink data signals. To drive a system with a data signal, use the Electrical Sources library with a Controlled Current Source or Controlled Voltage Source. Many of the SimPowerSystems blocks also input or output Simulink signals, so it depends a lot on what you are trying to do.
