 2. Run `./install-nghdl.sh` It will install ngspice from source code and put it in $HOME.
 3. Set ngspice path in `.bashrc` file. Add `export PATH=/home/{your-username}/ngspice-26/install_dir/bin:$PATH` line in .bashrc
 
+
 ##Few words about installed code structure.
 1. Ngspice will be installed in home directory $HOME. If you already have ngspice-26 directory there it will take its backup.
 2. Source code for all other file will be present in ~/.esim-nghdl
 3. symlink nghdl is stored in /usr/local/bin
 
+
 ##How to use?
 1. Run nghdl in command terminal.
 2. Upload your vhdl file.
 3. Model will be created with name of your vhdl file. It can be seen under (~ngspice-26/src/xspice/icm/ghdl/)
 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.
