1. A non-transitory computer readable medium having stored thereon a computer-readable encoding of a semiconductor integrated circuit (IC), the computer-readable encoding of the IC comprising encodings of:
a functional transistor, having an output configured to provide an electrical current;
a ring oscillator (ROSC) circuit, located proximate to the functional transistor and having an oscillation frequency in operation, wherein the ROSC has an input coupled to receive the electrical current from the output of the functional transistor; and
a processor, configured to determine one or more operating conditions of the functional transistor based on the oscillation frequency of the ROSC.
