How connet 74LS166 with 8051mcu in multisim 10

[inew]

I use a 74lLS166 in my design .but 74LS166 can't work in multisim 10.

How connect 74LS166 with 8051mcu in multisim 10?

Thanks for your answer.

Maybe you have some problems with the power supply. VCC or 5V ? GND, DGND or AGND ?

And the capacitors form the  crystal are "a little bit" strange.

Holy crap........10 FARADS of capacitance for a crystal resonator......um there isn't a snowballs chance in hell that would work.   Change them to 27pF.

The Problem still exists. Can you show me some correct circuit wich include the 74LS166 and 8051?
