3Verifying 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.
