    Hey Guys,
    I am using proteus8 making a circuit in which pic16f877a pin11(Vcc) is connected to other circuit and pin32(also Vcc) connected to other pin
    so,
    First i have to visible all pins of controller
    second i have to connect Vcc(11 &32) seperate because they are internally connected????

    Hidden pins can be connected to other nets by selecting "Hidden pins" in the device property pages...

    First create a voltage rail... Then tell ISIS to connect the hidden pin/s to the rail of your choice..

    can u please elaborate???
    and how i separate the by default connected pins such as pic16f77a vdd(11 & 32) & vss(12&31)

    I dont think you can separate the two pins on the micro!! They are internally connected in the real world...

    What benefit would it be to have them separate in ISIS??? Vdd is as one.. and Vss is as well!!

    Both pins are connected by default to 5v...

    And if i want to connect PIC16F877A vdd(11&32) pin such as i want to connect pin11 to other circuit and pin 32 to other circuit but separately??????

    But it wont be separate!!! Pin 11 is connected to pin 32 internally.... it would be no different than connecting your other device to 5V on it's own!

    Ah!! This is different! The pic18 is using RB6 to determine if there is a valid chip in the test socket!!! If RB6 is high, then there is a 40 pin pic in the test socket... Otherwise there is no chip or the wrong chip in the socket....

    You wouldn't need to simulate this... To create a circuit ( after simulating ) you would need to create a simple test socket, that's if you are taking the circuit into ARES...

    but i think there is no test socket which i can replace for a microcontroller (40pin) because it has 0.6inch distance between the two sides
