ForceDcCurrent(ISemiconductorModuleContext, string[], double, double, double)

Forces the specified DC current on all pins and/or pin groups specified. Both DCPower and Digital PPMU pins are supported. If a value is provided to the settlingTimeInSeconds input, the method will wait the specified amount of settling time before continuing. The absolute value of voltage limit will be applied symmetrically (i.e if voltageLimit = 1, the output voltage will be limited between -1V and +1V). An exception will be thrown if the specified limit value is outside the high-end of the voltage limit range for any of the mapped instruments. For Digital PPMU pins, since the voltage range of the digital pattern instruments is typically not symmetrically (i.e. -2V to 6V), the low-end of the applied voltage limit will be coerced to within range (i.e if voltageLimit = 3, the output voltage will be limited between -2V and +3V).
