Abstract
Techniques for using a speed measurement circuit to measure speed of an integrated circuit. The speed measurement circuit includes a ring oscillator and a counter circuit. The ring oscillator includes an AND gate with an inverting input and a non-inverting input. The ring oscillator also includes a programmable interconnect point context (PIP-context) having a first programmable interconnect point (PIP), a first interconnect, a second PIP, and a second interconnect coupled in series. The ring oscillator also includes a third interconnect and a third PIP coupled in series with the PIP-context and with an inverting input of the AND gate. The counter circuit is coupled to an output of the AND gate and configured in the programmable integrated circuit.
