1. A simulation test system for a vehicle electronic component comprising:

  • at least one attenuation probe that is connected to input lines of operating sample components in a state where they are electrically connected to the vehicle;

    a simulation unit includinga data collector that has multi-channels connectable to the attenuation probe and periodically stores and classifies input and output waveforms input in real time through the multi-channels, together with a sampling time and channel information for each waveform wherein the waveforms are classified based on at least road conditions at the time the waveform was generated, anda waveform generator, in communication with the data collector, that not only reproduces selected waveform data into original waveforms through the multi-channels using the waveform data stored by the data collector but also synchronously reproduces the waveforms for each channel; and

    an amplifier configured to amplify the waveforms reproduced in the waveform generator and input the amplified waveforms into a test component to simulate one or more driving conditions, wherein waveforms are searchable based on at least the associated road conditions at the time the waveform was generated.
