Dual gates in Multisim

Solved!
Go to solution

Are there dual gates in Multisim. For example can I swap a negative AND for an OR gate? Are there any negative gates in Multisim? Negative AND, negative XOR...

 

Thanks

Hi Curtis123,

 

You'll find them in the Master Database -> Misc Digital

Hi Pedro,

 

Thanks for your help but I still can not find a negative gate even in the Misc Digital area of the Master database. These are not NOR or NAND as they have inversion on the output. I am looking for negative devices that have inversion on the input. For example swapping an OR gate for its De Morgan equivalent Negative AND.

 

Thanks

Curtis123,

 

I understand, in that case, you'll need either to use a NOT before or create your own component following the tutorial below:

Thanks again Pedro.

 

I have created the gates that I require.

 

Cheers,

Would you be able to share the Dual Gates you created?  Is there a way to export and import them?  I wanted to be able to place gates with demorgan equivalents to teach bubble-matched schematic drawing techniques.  I'd love to use a library of these gates if someone has already gone to the trouble of creating them.
