Abstract
A block clock and initialization circuit for a programmable logic block in a complex very high density programmable logic device generates a plurality of block clock signals and block initialization signals for elements in the programmable logic block. The block clock and initialization circuit includes a block clock generator circuit and a block initialization circuit. The block clock generator circuit receives a first set of product terms in a plurality of product terms and a plurality of clock signals as input signals. In response to the input signals, the block clock generator circuit generates output signals on a plurality of block clock lines. The block initialization circuit receives a second set of product terms in the plurality of product terms as input signals. In response to the input signals, the block initialization circuit generates a plurality of output signals on the block initialization lines.

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.
