Executing DC Test
Retrieving and
Judgement of Result
Defining Relay Connection:
•
relay1 is an object name to which relay settings of the PPMU(s)
will be set, status is a member function to specify the status of
relays per pin (use the specifier, PPMU_ON to connect PPMU relays
and ALL_OFF to disconnect all the relays of the PMUs), wait is a
member function to specify a wait time after the relays are opened
or closed.
Defining Measurement Mode:
•
measure1 is an object name to which measurement mode of the
PPMU(s) will be set, execMode specifies one of the following
measurement mode:
mode
TM::GPF or "GPF"
TM::PPF or "PPF"
TM::PVAL or "PVAL"
In the step of "Setting up DC Test", the PPMU_SETTING,
PPMU_RELAY and PPMU_MEASURE APIs define a set of test
conditions for each setting, called DC Task. To perform a
measurement, define and execute a sequence of the DC tasks,
called Task List. For this purpose, first, use the TASK_LIST API as
shown below:
•
Definting a task list:
TASK_LIST tasks1;
tasks1.add(setting1).add(relay1).add(measure1);
• Executing a test:
tasks1.execute();
where, task1 is an object name that corresponds to a task list
name, setting1,relay1 and measure1 are objects defined with
the PPMU_SETTING, PPMU_RELAY and PPMU_MEASURE APIs to be
performed. The added DC tasks will be executed by the execute
member function sequentially.
For retrieving measurement results of the DC test that achieved
with the execute member function of the TASK_LIST API, use a
member function of the PPMU_MEASURE API and TEST API as
shown below:
•
Retrieving a measurement value per pin:
DOUBLE Ic = measure1.getValue("pin1");
•
Judgement of retrieved measurement value:
TEST("pin1","testname1", Ic);
where, Ic is a variable to store the returned value, measure1 is
the PPMU_MEASURE class object that holds the measurement
results, and it was defined when the measurement mode is
