The following example shows how to specify PMU type for the
PMU_IFVM API.
Setting DC
Measurement
Parameters
This section describes only the main DC measurement parameters. For all
DC measurement parameters, see the related API of the Test Method
Programming Reference.
Force Current/Voltage
For PPMU or SPMU, you can specify the force current or force voltage
with the iForce and vForce member function of the PMU_IFVM or
PMU_VFIM API. For the DPS, the force voltage is set in a level setup file,
not using the DPS_VFIM API.
Limit Values
limits(): To use limit values that are set in the Parameter dialog box,
specify the test name for this parameter.
Settling Time
settling(): (For PMU only) Settling time specifies the time interval
between the PMU being programmed and the measurement being
performed.
Connection Mode
mode(): (For PMU only) This mode specifies the relay control pattern
and how to test multiple pins as shown bellow. You must specify a mode
for the measurement.
•For pin1 and pin_group2 connected to the Pin PMUs:
PMU_IFVM("pin1, pin_group2");
or
PMU_IFVM("pin1, pin_group2", TM::PPMU);
•For pin1 connected to the High Precision PMU:
PMU_IFVM("pin1", TM::SPMU);
Mode AC Relay Control
