Hi Mayur,
I understand that you want to implement UDS using Simulink without indulging with any third party library blocksets.
To implement the Unified Diagnostic Services (UDS) protocol using Simulink without using third-party library blocksets, you can follow these general steps:
1. Create the UDS message structure: Define the structure of the UDS messages you want to send and receive. This includes the message identifier, data length, and data bytes. You can use Simulink Signal Builder or a MATLAB script to define the message structure.
2. Implement the UDS protocol logic: Use Simulink blocks to implement the UDS protocol logic. This involves handling the different UDS services, such as diagnostic session control, communication control, and read/write operations. You can use Stateflow charts or Simulink blocks like Switch Case, If-Else, and Logical Operator to implement the UDS protocol logic.
3. Implement the transport layer: UDS protocol relies on a transport layer for communication. You can use Simulink blocks like CAN Transmit and CAN Receive to implement the transport layer. If you are using a different communication protocol, such as Ethernet or LIN, use the appropriate Simulink blocks for that protocol.
4. Handle UDS responses: After sending a UDS request, you need to handle the corresponding response. Use Simulink blocks to decode the response and extract the relevant information. Depending on the response, you may need to handle error conditions or perform additional operations.
5. Test and validate: Once you have implemented the UDS protocol logic, test it with sample requests and verify that the responses are as expected. You can use Simulink test benches or create test scenarios to validate the UDS implementation.
Note that implementing UDS without third-party library blocksets may require more effort and customization compared to using dedicated UDS blocksets. However, Simulink provides a wide range of blocks and tools that can be used to build the UDS functionality from scratch.

I hope this helps!
