Abstract: Methods, systems, and circuits for forming and operating a global hierarchical clock tree are described. The global hierarchical clock tree may comprise a clock circuit that operates to provide clock signals to a core circuit surrounded by the clock circuit. The clock circuit may include two or more first and second clock generator modules to generate a first and a second set of clock signals, respectively. The first and second clock modules may be located so that the first set of clock signals experience approximately equal first latencies and the second set of clock signals experience approximately equal second latencies. Additional methods, systems, and circuits are disclosed.

Abstract: Methods, circuits and systems may operate to generate a reset signal at an input reset block and synchronously distribute the reset signal, via a number of pipelined reset blocks, to multiple ports of a core circuit. The reset signal may be transmitted successively to each of the pipelined reset blocks to provide delayed reset signals having delay times. The delay times may be based on locations of the pipelined reset blocks in the reset circuit. One or more of the delayed reset signals may be programmably coupled to one or more ports of the core circuit. Additional methods, circuits, and systems are disclosed.
