  • Patent number: 11216022
    Abstract: 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 (“CSQ”) for clocking logic blocks in a clock region. Also, a set of neighboring clock signals (“NCSs”) 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 (“SCSs”) generated from the RCSs with a low CSQ for clocking logic blocks with less time-sensitive logic operations.
