+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without

+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions

+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# TestSetup-Intel16OpenTitanSoC
+
+This repository provides a fully open-source test setup solution for an OpenTitan chip tapd-out in Intel 16nm with OpenROAD-generated OpenTitan subset instances and 24 OpenFASOC-generated temperature sensor instances. The setup is highly automated with Python and open-source libraries, where the chip is controlled through low-cost commercially-available microcontroller.

+**Author:** [Ming-Hung Chen](https://www.linkedin.com/in/ming-hung-chen-85ab311b6/) from the [University of Michigan, Ann Arbor](https://micl.engin.umich.edu)
+\
+**Advisor:** [Mehdi Saligane](https://www.linkedin.com/in/mehdi-saligane/) from the [University of Michigan, Ann Arbor](https://micl.engin.umich.edu)
+
+## 1. Prerequisites
+### 1.1 **Host Computer**
+A host computer with Windows 10 operating system is required. Either a desktop or a laptop works.
+
+### 1.2 **Python**
+Please install the latest version of [Anaconda](https://www.anaconda.com/products/individual) on the host computer and use Spyder for running the test scripts.
+
+## 2. Test Setup
+### 2.1 **PCB for the Chip**
+The printed circuit board (PCB) could be as simple as one that directly connects all the chip I/Os to headers and power supplies to SMA or banana connectors. Level conversion from 3.0V to 1.2V is required as the chip uses 1.2V I/O voltage. Intel provides BGA packages, including fabricated  chip and solderless socket. The PCB designed for validating this setup is shown below as a reference:
+
+<img src="./img/PCB.png" width="600">
+Fig. 1. Top view of the PCB
+
+### 2.2 **FT232H USB-to-GPIO/SPI Microcontroller**
+One [FT232H](https://www.adafruit.com/product/2264#description) USB to GPIO, SPI microcontroller from AdaFruit are needed in this setup for controlling the chip. Please purchase it online from Adafruit. After getting the board, follow this [page](https://learn.adafruit.com/circuitpython-on-any-computer-with-ft232h/windows) `Plug in FT232H & Fix Driver with Zadig` part to install driver for the microcontroller using [Zadig](https://zadig.akeo.ie) on the host computer.
+
+After the driver is installed, open an Anaconda prompt on the host computer, install [pyftdi](https://eblot.github.io/pyftdi/api/spi.html) libraries:
+
+```  
+pip install pyftdi 
+```
+
+After the installations, connect the microcontroller to the PCB via jumper wires according to `PinMap.md` in this repository. The pin numbers of bridge boards are already printed on-board, like what is shown in Fig. 2, while the chip I/O names are printed on the top of the PCB shown in Fig. 1. After connecting the chip I/Os, also remember to connect the ground pins to the PCB ground for a common ground.
+
+<img src="./img/FT232H.jpg" width="600">
+Fig. 2. FT232H USB-to-GPIO/SPI Microcontroller
+<br /><br />
+
+The last step for setting-up the microcontroller is to connect them to the host computer via USB cables and figure out what their USB addresses are. Use `find_usb_addr()` function in `tools.py` in this repository to achieve that. After that, replace line `7` in `opentitan_ctrl.py` and `sh1122_ctrl.py` with the correct USB addresses you get.
+
+## 3. Running the Scripts for Automated Testing
+
+### 3.1 **opentitan_demo.py**
+This script provides a sanity check for testing the chip. The script will ask the user to turn on the clock source and power supplies to the chip. Then the script will make the chip program SH1122 LCD display with SPI protocol. The cool logo should be shown like Fig. 3.
