Design a VHDL entity named andnand to specify the interface

of the following circuit:

 

 

 

 

 

 

 

 

 

   Use std_logic for the port signal types of all input and output pins

The VHDL description of the andnand entity should resemble the following:

Another Example :

 

Design a VHDL architecture to specify the internal implementation of andnand

 

 

 

 

 

 

 

 

   Name the architecture synthesis1

 

 

The VHDL description of the andnand architecture should resemble the following:
