[Moved]: how to use multiple power source in proteus 8 simulation!

I am building a circuit and I want to simulate the circuit first with proteus 8 before building it. I want to connect my 12v power source to the input of my 5v (7805) regulator and the regulator output to power a pic16f84a micro-controller and sensor. The pic mcu power pins is not visible but is automatically connected to a 5v supply. My problem is that when I connect headers to my 12v and 5v points, they are all connected together. that is, they are continuous and is not desirable.
How can I use multiple power source in proteus without conflict?

I figured it out. The micro-controller by default is connected to a 5v power and ground. I used a 5v regulator to interface between the 12v and the default 5v supply. previously, the 5v and the 12v will be continous without using an interface
