Abstract
The skew of a circuit within a clock pulse distributing network is determined by establishing a closed loop circuit including the circuit under test. A sampling period is established such as by a counter actuated by the clock pulses. During that sampling period, the number of pulses recurring within the closed loop circuit are counted in yet another counter. The count is then useful not only to indicate the magnitude of the circuit skew but also allows optimization of the delay introduced to the circuit under test during normal operation. The skew is thus determined dynamically under typical machine environment situations.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
