3Verifying System Functionality
The system functional verification test is a standard IC-CAP measurement
and simulation procedure. The system performs DC and S- parameter
extraction, optimization, and simulation using a fixed 10 dB attenuator as
the device under test (DUT).
The procedure provided in “Performing the System Functional Verification
Test” confirms:
•the IC-CAP software can c ommunicate with and control the system
instrumentation via GPIB (through the LAN/GPIB gateway, if so
configured)
•the system can make measurements and display the results
•the IC-CAP software can simu late data
•the IC-CAP software can converge the simulated data with the
extracted (measured) data
The system applies forward and reverse current to the attenuator a nd
monitors voltage at the attenuator’s input and output. IC-CAP then uses
the measured data to model the device- intrinsic resistances and
transmission line delay.
