Changing the Power voltage of the CHIPS in PROTEUS

[epilot]

Hi folks.

Sorry, BUt How can I change the default values for th voltages of a Chip?
For instance I am using a TL072 OP-AMP in Proteus but The default voltage for it seem to be 5V even when I connect the higher voltages to pins #8 and 4 of the said chip.

Or for some other chips There in no voltage pin connected to the chip so that I could connect it to a voltage and seem to work by the default voltage, SO how to to solve the problem for such Chips?

Thank a bunch

in devices that have the supply pin you can use a DC power source and just set the value you want


When the supply pins are hidden then there is a power net assigned to them, you can assign a different net if you want using the following


The design power rails are shown in design -> configure power rails menu, you can add your own there
open the hidden pin of your device and connect the pin VCC to your selected net name, for example


then open the power rail , create a new power source , for example VCC_33 and set the voltage to 3.3v, then add the net that your component is connected to (in my case 33V_NET) to the created power source and you are done
