It processes a sequence of input bytes and generates the expected `done` signal and `out_bytes` output. The `process_input_bytes` function takes a list of input bytes and a list of reset signals, and returns the expected `done` signal and `out_bytes` for each clock cycle. The example usage demonstrates how to use this function with a sample input sequence. ------------------------------ 2026-01-07 12:49:27.9 | INFO | [fsm_ps2data] [TBgen] stage_3 ends (23.73s used) DEBUG: Connecting to https://dashscope.aliyuncs.com/compatible-mode/v1...

It processes the input byte stream and generates the expected `done` and `out_bytes` signals based on the rules provided.

Below is the corrected Python code for the `GoldenDUT` class, incorporating the necessary changes to handle the reset and state transitions correctly. The structure of the class and its methods remain the same, but the logic within the `load` method has been updated. ```python class GoldenDUT: def __init__(self): self.state_reg = 'idle' self.first_byte_reg = 0 self.second_byte_reg = 0 self.third_byte_reg = 0 self.out_bytes_reg = 0x000000 self.done_reg = False def load(self, signal_vector): reset = signal_vector['reset'] in_signal = signal_vector['in'] if reset: self.state_reg = 'idle' self.first_byte_reg = 0 self.second_byte_reg = 0 self.third_byte_reg = 0 self.out_bytes_reg = 0x000000 self.done_reg = False else: if self.state_reg == 'idle': if (in_signal & 0x08) != 0: # Check if in[3] is set self.state_reg = 'first_byte_received' self.first_byte_reg = in_signal else: self.state_reg = 'idle' elif self.state_reg == 'first_byte_received': self.second_byte_reg = in_signal self.state_reg = 'second_byte_received' elif self.state_reg == 'second_byte_received': self.third_byte_reg = in_signal self.state_reg = 'third_byte_received' elif self.state_reg == 'third_byte_received': self.done_reg = True self.out_bytes_reg = (self.first_byte_reg << 16) | (self.second_byte_reg << 8) | self.third_byte_reg if (in_signal & 0x08) != 0: # Check if in[3] is set self.state_reg = 'first_byte_received' self.first_byte_reg = in_signal self.second_byte_reg = 0 self.third_byte_reg = 0 self.done_reg = False # Reset done flag for new message else: self.state_reg = 'idle' self.done_reg = False self.out_bytes_reg = 0x000000 else: raise ValueError("Invalid state: {}".format(self.state_reg)) def check(self, signal_vector): expected_done = self.done_reg expected_out_bytes = self.out_bytes_reg observed_done = signal_vector['done'] observed_out_bytes = signal_vector['out_bytes'] if expected_done != observed_done or (expected_done and expected_out_bytes != observed_out_bytes): print(f"Scenario: {signal_vector['scenario']}, expected: done={expected_done}, out_bytes={expected_out_bytes:06x}, observed: done={observed_done}, out_bytes={observed_out_bytes:06x}") return False return True ``` ### Explanation of Changes: 1. **Reset Handling:** - The `reset` signal now correctly resets all internal registers and sets the FSM to the `idle` state. - If the `reset` signal is high, the FSM will transition to the `idle` state and clear all internal registers, regardless of the current state. 2. **State Transitions:** - After the FSM has captured the third byte and signaled `done`, it checks the next input byte. If the next input byte has `in[3] = 1`, it transitions to the `first_byte_received` state and starts capturing a new message. Otherwise, it transitions back to the `idle` state. - The `done` flag is reset when a new message is started, ensuring that the `done` signal is only asserted for the correct 3-byte message. These changes should address the issues in the failed scenarios and ensure the FSM behaves as expected. ------------------------------ 2026-01-07 12:58:45.7 | INFO | [fsm_ps2data] [TBcheck] [corrector] naive corrector mode ends; conversation and codes saved 2026-01-07 12:58:45.7 | INFO | [fsm_ps2data] [TBcheck] [discriminator] Discriminating the testbench, NO.1 discrimination 2026-01-07 12:58:46.2 | NEGATIVE | [fsm_ps2data] [TBcheck] [discriminator] TB_discriminating finished, TB failed, wrong scenarios: [2 6 8], scenario pass ratio: 7/10 2026-01-07 12:58:46.2 | INFO | [fsm_ps2data] [TBcheck] wrong scenarios not decreased for 1 times (3 = 3), continue the correction 2026-01-07 12:58:46.2 | INFO | [fsm_ps2data] [TBcheck] [corrector] naive corrector mode begins DEBUG: Connecting to https://dashscope.aliyuncs.com/compatible-mode/v1...

Based on our previous conversation and the provided hints, here is the corrected Python code for the `GoldenDUT` class.

When `reset` is high, the FSM transitions to the `idle` state, and all internal registers are reset. 2. **State Transitions:** - In the `load` method, the state transitions are managed more carefully: - When in the `idle` state, if `in[3]` is set, the FSM transitions to `first_byte_received` and updates `first_byte_reg`. - When in the `first_byte_received` state, the FSM transitions to `second_byte_received` and updates `second_byte_reg`. - When in the `second_byte_received` state, the FSM transitions to `third_byte_received` and updates `third_byte_reg`. - When in the `third_byte_received` state, the `done` flag is set to `True`, and `out_bytes_reg` is updated. If `in[3]` is set, the FSM transitions to `first_byte_received` and updates `first_byte_reg`. If `in[3]` is not set, the FSM transitions to `idle`. 3. **Done Flag Management:** - The `done` flag is set to `True` only after the third byte is received. - The `done` flag is reset to `False` when the FSM transitions to `idle` or `first_byte_received`. This should ensure that the FSM behaves correctly according to the specified requirements and handles the `reset` signal and state transitions appropriately. ------------------------------ 2026-01-07 12:59:45.1 | INFO | [fsm_ps2data] [TBcheck] [corrector] naive corrector mode ends; conversation and codes saved 2026-01-07 12:59:45.1 | INFO | [fsm_ps2data] [TBcheck] [discriminator] Discriminating the testbench, NO.2 discrimination 2026-01-07 12:59:45.9 | NEGATIVE | [fsm_ps2data] [TBcheck] [discriminator] TB_discriminating finished, TB failed, wrong scenarios: [2 6 8], scenario pass ratio: 7/10 2026-01-07 12:59:45.9 | INFO | [fsm_ps2data] [TBcheck] wrong scenarios not decreased for 2 times (3 = 3), I give up, quiting the funccheck stage... 2026-01-07 12:59:45.9 | INFO | [fsm_ps2data] [TBcheck] self funccheck finished.
