A system includes a first cross-point switch receiving a first plurality of clock inputs and outputting a first plurality of clock outputs, a first plurality of buffering devices receiving the first plurality of clock outputs and outputting a first plurality of buffered clock signals synchronized with each other, a first plurality of connectors receiving the first plurality of buffered clock signals and outputting a plurality of blade signals to a plurality of blades. Each blade includes a plurality of programmable logic devices, an operation of which is synchronized based on the first plurality of clock inputs. Each blade includes a second cross-point switch to receive a blade signal of the plurality of blade signals. The second cross-point switch outputs a second plurality of clock outputs based on the received blade signal, and the second plurality of clock outputs are provided to the programmable logic devices.

Synchronized clock signals for circuit emulators

A mid-plane board including a first connector configured to receive a first signal from a first circuit board is provided. The mid-plane board includes a second connector configured to provide the first signal to a second circuit board. The first circuit board forms a first plane and the second circuit board forms a second plane, and the first plane and the second plane are substantially parallel. The mid-plane board also includes a cutout configured to allow a coplanar connector to bridge the mid-plane board and provide a second signal from the first circuit board to the second circuit board. The second signal is a high-end signal and the first signal is a low-end signal, and the mid-plane board is disposed on a plane substantially orthogonal to the first circuit board and the second circuit board.
