 ## What exactly interfacing of ngspice ghdl do?
 Ngspice support mixed mode simulation. It can simulate both digital and analog component.

 4. You can use this model in your netlist.
 
-##LIMITATION:
-1. You can use only one output port in your file.
-2. All the port should be std_logic_vector only.
-3. We can use only one instance of code model in netlist.

-##FUTURE WORK
-1. Make changes to have more than one output.
-2. Making changes to include use of more than one instance of code models.
-3. Interfacing it with eSim formely known as Oscad so that we can use it in our schematic.
 
+##FEATURES:
+1. Support for 512 digital models.
+2. Support for digital models upto 64 output ports/pins.
+3. Multiple instances of same digital model.
