During measurement, PLT will control the instrument using the
ammeter_driver
describes the instrument selection settings found by the
ammeter_driver
DLL,
describes
the settings used for each of the peripheral current measurement tests and
describes the
current measurement options for each sleep state.
Note:
Modifications in the production test firmware are mandatory in order to achieve the correct
current consumption of a specific hardware design (IC and peripherals) for each sleep state. Running
the default firmware without any modifications specific for the hardware design, may cause increased
current consumption.
Peripheral Current Measurement Tests
can have multiple instances with different settings. Tests can
be added and removed using the two buttons (e.g.,
and
in
) at the bottom right side
of each panel.
Note:
When adding or removing a test, all settings are refreshed with the values written to the XML
file, meaning that any unsaved settings will be lost.
Table 46: Current Measurement Tests
Option
Description
Enable
This option enables all Current Measurement tests, which include:
●
Peripheral current measurements
●
Extended sleep current measurement
●
Deep sleep current measurement
Only one of the Extended/Deep sleep current measurements can be selected.
Instrument
Select the Ammeter instrument DLL name. Names are shown only if an ammeter
DLL exists in the project
ammeter_instr_plugins
folder.
Interface
The interface of the instrument to be used by the driver.
Enable single DUT
current
measurement when
failed
If this option is enabled and if the measurement taken is outside of the limits, PTL will
reset all devices and begin a firmware download and measure the current to each
device separately, in order to identify which exact device failed.
Table 47: Current Measurement Test
– Peripheral Current Measurement
Option
Description
Enable
This option enables the specific peripheral current measurement test.
Test name
The name assigned to each test. The assigned name will be shown on the tab and
next to it an indication showing whether the specific test is enabled or not.
Single Device
If this option is enabled, PLT will measure the current consumption one device at the
time. Initially, it will power off all DUTs. It will then power on one by one, download
firmware and measure the current individually. This procedure takes a lot of time. It
should only be used for production setup purposes, to identify the correct limits by
measuring multiple DUTs and taking the average.
Shunt resistor
The value of the shunt resistor used for peripheral measurement. Applicable only if a
voltmeter or a NI-DAQ is used to measure current instead of a DMM. Values from 0
to 9999 are supported.
Wait time
The time in ms the PLT will wait before taking a current measurement, after it has
sent an instruction to the DUTs to go into a specific sleep state. Supported values are
1 to 500000 ms.
Range
The range value in Ampere units that the ammeter will operate. Supported values are
0 to 9999 and default value is 0.001 A. When the
ammeter_scpi.dll
is used, if this
value is set to zero, the instrument will use the automatic range functionality.
