3 Verifying System Functionality
Understanding the System Functional Verification Test
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 communicate 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 simulate 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 and
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.
