Project 1- Traffic Jam Assistant Feature

1. Model Setup

• Use MATLAB Simulink and ensure compliance with MBD guidelines.
• Enable Embedded Coder for code generation.
• Create and link a Simulink Data Dictionary for managing calibration signals.
• Generate a Model Advisor Report before proceeding with code generation.

2. Implement Voltage Range Check (Requirement 1)

• Inputs:
  • Input_Voltage (uint8, Range: 0-255)
  • VOLTAGE_MINIMUM_RANGE (uint8, Default: 30)
  • VOLTAGE_MAXIMUM_RANGE (uint8, Default: 50)
• Logic:
  • If Input_Voltage is within the range VOLTAGE_MINIMUM_RANGE ≤ Input_Voltage ≤ VOLTAGE_MAXIMUM_RANGE, set Optimum_Voltage = 1 (true).
  • Otherwise, set Optimum_Voltage = 0 (false).
• Output:
  • Optimum_Voltage (boolean, 0-1)

3. Implement DisplayUnit Subsystem (Requirement 2)

• Inputs:
  • Optimum_Voltage (boolean, 0-1)
  • Input_Switch (boolean, 0-1)
  • Enable_Display (uint8, Range: 0-255) → Saturate to 0-7
• Calibration Signals:
  • ON_MODE = 1, OFF_MODE = 2, STANDBY_MODE = 3, NO_DISPLAY = 0
  • INTERRUPT_1 = 1, INTERRUPT_2 = 1
• Logic Flow:
  • Step 1: Saturate Enable_Display between 0-7.
  • Step 2: Multiport Switch Logic
    • Inputs 1 & 2 → ON_MODE
    • Inputs 3 & 4 → OFF_MODE
    • Input 5 → STANDBY_MODE
  • Step 3: Switch Block Logic
    • First Input: Output from Multiport Switch.
    • Second Input:
      • AND Gate checks:
        • NOT(Input_Switch)
        • Optimum_Voltage
        • INTERRUPT_1 == INTERRUPT_2
    • Third Input: NO_DISPLAY
  • Output: Output_Display (uint8, 0-255)

4. Validation & Testing

• Run Model Advisor Checks to ensure MAAB guideline compliance.
• Simulate with different test cases:
  • Input_Voltage inside & outside range.
  • Enable_Display with different values (0-7).
  • Input_Switch toggling.
• Check outputs & verify logic.
• Generate Embedded C code using Embedded Coder.
