 ### ADAC test suite
 
-The ADAC test suite checks if a device-side implementation conforms to the behavior described in the ADAC specification. The tests are self-checking, portable C-based tests with directed stimulus. The tests are expected to run on the host platform only. The tests drive the commands from the host platform through the debug link and verify the response obtained from the target platform.

-## Test Suite Execution
-
-The current release provides a reference implementation of ADAC target which communicates with the host platform using Unix sockets. To execute the test suite, follow the steps below:
-
-    cd psa-arch-tests/secure-debug/psa-adac
-    make native
-
-To launch the target to run as a server instance, run the target executable in another terminal as shown:
-
-    cd psa-arch-tests/secure-debug/psa-adac
-    ./build/native/Debug/psa_adac_server coms.socket tools/test/resources/chains/chain.EcdsaP256-3
-
-To run the test suite, execute the following command from your host build directory <host_build_dir>:
-
-    ./psa_adac_test ../psa-adac/tools/test/resources/keys/EcdsaP256Key-3.pem \../psa-adac/tools/test/resources/chains/chain.EcdsaP256-3 ../psa-adac/coms.socket
+For running the test suite on the emulation platform, see the [Readme](platform/hosts/emulation/unix_socket/README.md).<br/>
+For running the test suite on the Musca-b1 hardware platform, see the [Readme](platform/hosts/musca_b1/memw_pyocd/README.md).<br/>
 
 Note:
  - See the psa-adac directory for information on other target platforms.
  - The keys and the certificate credentials for a supported cryptosystem can be generated using the tools provided in the psa-adac repository.
- - The test suite is designed to run once per supported cryptosystem. You must ensure that the device must be provisioned with the correct certificates installed in the device's RoT.

+    make native
+~~~
+
+## Build steps for host image
+
+To build ADAC test suite, execute the following commands: <br/>
+~~~
+    cd psa-arch-tests/secure-debug
+    mkdir <host_build_dir>
+    cd <host_build_dir>
+    cmake ../ -G"Unix Makefiles" -DTARGET=emulation -DSUITE=ADAC

+# Verifying test suite on Musca-b1 hardware platform
+
+## Prerequisites
+
+Before executing the test suite on host, ensure that the following requirements are met:
+
+- Python 3.7.1 and above with pyOCD is installed.
+- Debug probe is connected from the target to the host system using a USB cable.
+- The target image is flashed onto the board.
+
+## Build steps for target image
+
+The steps to build and flash the image for the musca-b1 hardware target are described in the psa-adac repository in ports/targets/musca-b1/README.md.
+
+## Build steps for host image
+
+To build ADAC test suite, execute the following commands: <br/>
+~~~
+    cd psa-arch-tests/secure-debug
+    mkdir <host_build_dir>
+    cd <host_build_dir>
+    cmake ../ -G"Unix Makefiles" -DTARGET=musca_b1 -DSUITE=ADAC -DLINK_LAYER_COMM=memw_pyocd
+    cmake --build .
+~~~
+
+## Test Suite Execution
+
+Arm uses UDP sockets to transmit and receive test information from the host to pyOCD. pyOCD is used for communication with the target board. The pyOCD script communicates with the board using a memory window-based debug mailbox.
+To launch the pyOCD script, run the following in another terminal as shown:
+~~~
+	cd platform/hosts/musca_b1/mem_pyocd
+	python host_connect.py <port_no>
+	where:
+        - <port_no>          - The port number for communicating between host and pyOCD. Default is 7777
+~~~
+
+To run the test suite, execute the following command from your host build directory <host_build_dir>:
+~~~
+    ./psa_adac_test ../psa-adac/tools/test/resources/keys/EcdsaP256Key-3.pem \../psa-adac/tools/test/resources/chains/chain.EcdsaP256-3 <ip_address> <port_no>
+	where:
+		- <ip_address>       - The IP address of the network connection running the server instance
+        - <port_no>          - The port number for communicating between host and pyOCD. Default is 7777
+~~~
