摘要： A method for designing a system on a target device utilizing field programmable gate arrays (FPGAs) includes identifying a group of components associated with a critical signal in the system. A first copy and a second copy of the group of components are generated where the first copy is driven by a first signal at a first state and the second copy is driven by a second signal at a second state. The system is configured to select an output of one of the first copy and the second copy in response to the critical signal.

摘要： An expandable arrow broadhead used for releasable attachment to one end of a hollow arrow shaft. The broadhead includes a sliding shaft with a pointed tip and tip base having two or more of cutting blades mounted thereon. Each of the blades includes an outer cutting edge and an inner edge with a beveled cam surface and locking notch therein. A portion of the sliding shaft is slidably received inside a hollow collar. The collar is attached to a sliding shaft housing. The sliding shaft housing is attached to an arrow shaft insert. The arrow shaft insert is adapted for receipt inside one end of the arrow shaft. In a retracted position, the blades are disposed next to and parallel to the length of the sliding shaft. When the pointed tip engages a target, the sliding shaft moves inwardly and rearwardly sliding inside the collar and inside a sliding shaft bore hole in the sliding shaft housing. As the sliding shaft moves rearwardly, the beveled cam surface of the blades engages a portion of the collar, which moves the blades outwardly with locking notch securing the blades in an extended position.
