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.

RPM_configure

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.

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.
