+##  Structure
+While it is possible to have a stand-alone notebook, we have decided to split up the code into modules to improve readability and documentation. The following outline the directory structure.

+```
+Suggest to setup following environment under `EDA_Tools`
+```
+%%install ngspice and other possible configuration files
+cd /home/EDA_Tools
+sudo pip3 install flake8
+sudo pip3 install setuptools-scm
+sudo apt update
+sudo apt install build-essential tcl8.6 tcl8.6-dev tk8.6 tk8.6-dev libx11-dev libcairo2-dev libxpm-dev
+sudo apt update
+sudo apt install flex
+sudo apt install bison
+sudo apt install libcairo2-dev libjpeg-dev
+sudo apt install ngspice
+sudo apt install gwave
+sudo apt-get install xterm
+sudo apt-get install vim-gtk
+sudo apt-get install build-essential tcl-dev tk-dev libcairo2-dev libncurses-dev libx11-dev
+git clone https://github.com/RTimothyEdwards/magic.git
+cd magic
+./configure
+make
+sudo make install
+```
+Open PDK Installation
+```
+%%download and install open pdk
+cd /home/EDA_Tools
+git clone https://github.com/RTimothyEdwards/open_pdks
+cd open_pdks
+./configure --enable-sky130-pdk --enable-sram-sky130
+make
+sudo make install
+make veryclean
+```
+
+%% Python Setup
+The `environment.yml` can be used as a reference for the packages required. Before running the notebook, ensure that the circuit-design tools and the required packages have been installed successfully. Additionally, create a textfile in SpeechCommands -> speech_commands_v0.02 -> noise_list.txt with the following content. This is used to add background noise to the data for a more robust result.
+```
+%% noise_list.txt
+_background_noise_/doing_the_dishes.wav
+_background_noise_/dude_miaowing.wav
+_background_noise_/exercise_bike.wav
+_background_noise_/pink_noise.wav
+_background_noise_/running_tap.wav
+_background_noise_/white_noise.wav
+```
