Notes

  • Net names (e.g., VOLTAGE_OUTPUT, POWER_RAIL) refer to names assigned when setting up your testbed
  • Voltage values are specified in volts
  • Only works with nets of type dac
  • Ensure the target DUT has DAC nets properly configured
  • DAC outputs provide precise voltage control for analog circuits
  • Supports both positive and negative voltage outputs
  • USB-202 channels can be specified as 0-1, DAC0-DAC1, or AOUT0-AOUT1
