 # Analog Spiking Neuron Circuit - Caravel Submission
 
 This is the Google/EFabless/Skywater Caravel submission of an [Analog Spiking Neuron Circuit.](https://ieeexplore.ieee.org/document/9184447) The submission also includes a SONOS transistor array.

 ## Neuron circuit
 The circuit in the original paper is in 130nm technology and has a vdd of 300mV. Skywater pdk is hybrid 180nm/130nm node where the minimum transistor length is 150nm.
 As a result vdd needs to be higher in order to get the circuit to work properly. In simulation 700mV seems to work well.

+# Installation
+To setup and install the repo for development:
+
+1. Install prerequisite tools:
+   1. Install [Magic VLSI Layout Tool](http://opencircuitdesign.com/magic/)
+      - Note: As of 12/7/2020 you must install Magic from source code. The packaged version will not work with OpenPDKS.
+   2. Install [KLayout](https://www.klayout.de/build.html)
+   3. Install [SkywaterPDK](https://github.com/google/skywater-pdk) and [OpenPDK](https://github.com/RTimothyEdwards/open_pdks) using [OpenLane](https://github.com/efabless/openlane.git)
+      1. Clone and Install OpenLane. This will also grab and install SkywaterPDK and OpenPDK for you.
+
+```shell
+export PDK_ROOT=(where pdks will be installed)
+
+cd $PDK_ROOT
+
+git clone https://github.com/efabless/openlane.git -b mpw-one-a
+
+cd openlane
+export OPENLANE_ROOT=$(pwd)
+make
+```
+
+‚Äč			2. Clone and uncompress the repo
+
+```shell
+git clone https://github.com/Bryce-Readyhough/caravel_UNCC_MPW_1.git
+make uncompress -j$nproc
+```
