A configurable semiconductor device ('CSD') is organized in four (4) quadrants able to perform user-defined logic functions via a clock fabric. The first quadrant, in one embodiment, includes a first serializer and deserializer (“SerDes”) region and a bank0 region for data processing. The second quadrant includes a second SerDes region and a bank5 region and the third quadrant contains a bank3 region and a bank4 region. The fourth quadrant includes a bank1 region and a bank2 region. The clock fabric is configured to provide a set of programmable or selectable clock signals with different clock speeds to various regions within the CSD.

Methods and apparatus for organizing a programmable semiconductor device into multiple clock regions

A field-programmable gate array ('FPGA') contains a configurable semiconductor organized in multiple clock regions with a clock fabric for facilitating user-defined logic functions. The clock fabric provides a set of regional clock signals ('RCSs') generated from a clock source with a high clock signal quality (&#x201c;CSQ&#x201d;) for clocking logic blocks in a clock region. Also, a set of neighboring clock signals (&#x201c;NCSs&#x201d;) or inter-regional clock signals are generated from a neighboring clock source(s) for clocking logic blocks in two neighboring regions. In addition, the clock fabric is operable to provide secondary clock signals (&#x201c;SCSs&#x201d;) generated from the RCSs with a low CSQ for clocking logic blocks with less time-sensitive logic operations.
