PMU_PCRAM_ulib user library
The user modules in this library are used in the characterization of PRAM elements.
PMU_PCRAM_ulib user modules
User module Description
pram_pulse_ilimit
Simplifies the generation of segments using the PMU, and collects forced
voltage and current values from both the ForceCh and MeasureCh channels.
The basic scenario used is a connection of the ForceCh to the high side of the
DUT while MeasureCh is connected to the low side of the DUT. The segments
are created based on the settings provided by the operator in the Volts and
Times input arrays. Measurements are returned through the voltage (VF and
VM) and current (IF and IM) output arrays for both channels.
pram_sweep
Provides an example of how the PMUs might be implemented in the
characterization of PRAM elements. The routine allows specification of four
pulses in one waveform: RESET, MEASURE, SET, and MEASURE. The
parameters of these pulses are determined by the user, and the SET pulse
amplitude can be swept to generate R-I and I-V graphs.

pmuulib user library
The pmuulib user library contains user modules for configuring the 4225-RPM for the designated
PMU channel. The next table lists and briefly describes the user modules.
pmuulib user modules
User module Description
RPM_configure
This user module configures the 4225-RPM for the designated PMU channel.
RPM_switch
This user module has been deprecated. Use the LPT command rpm_config() (on
page 13-124) for any RPM mode switching.
