INTEGRATED CIRCUIT CHARACTERISATION SYSTEM AND METHOD
First Claim
1. A method of characterizing an integrated circuit (IC) for comparison with a pre-defined system-level characteristic related to an aspect of IC operation, the method comprising the steps of:
- executing a test procedure on the IC that invokes the aspect;
invoking at least one operational bottleneck during said executing step to constrain operation of the IC to exhibit a system-level operation thereof related to the aspect;
collecting data generated via said test procedure in response to said bottleneck; and
comparing said system-level operation exhibited by said data for consistency with the pre-defined system-level characteristic.

Abstract
There is presented a system and method for characterizing an integrated circuit (IC) for comparison with a pre-defined system-level characteristic related to an aspect of IC operation, wherein a test procedure on the IC that invokes this aspect is executed, while at least one operational bottleneck is invoked to constrain operation of the IC to exhibit a system-level operation thereof related to the aspect. Data generated via the test procedure in response to the bottleneck is collected and the system-level operation exhibited thereby is compared for consistency with the pre-defined system-level characteristic.

-
23. The computer-readable medium according to claim 23, further comprising statements and instructions wherein operating the IC in an OS free environment comprises executing a revised open source operating system on the IC for which at least one parameter is removed which, in operation, obscures a native operation of the IC.
