    摘要: A method of performing a static timing analysis based on slack values to verify and optimize a logic design includes: selecting one or more circuits within the logic design having at least two inputs taking on a known value; identifying a critical input that controls an output arrival time of the selected circuit from among the inputs that take on the known value; determining one or more non-critical input of the circuit a required arrival time based on the difference between the arrival times of the critical and non-critical inputs; and computing the slack at a critical input based on the difference between the AT of the critical and non-critical inputs. The design optimization based on the slack defined by arrival time differences preferably uses a reverse merge margin design metric. The metric determines the exact required amount of improvement in the input arrival time of non-critical signals of a clock shaping circuit.

    摘要: An apparatus for universally supporting and positioning a rotating grinder wheel comprising a support base carrying a cage which rotates about a horizontal axis, and with a horizontally reciprocating frame mounted within the cage for rotation with the cage and reciprocating forwardly and rearwardly relative to the cage. A lever has one end universally pivotally connected to the frame, with the opposite end of the lever extending forwardly of the frame and carrying the rotating grinding wheel. A powered vertical guide means connected to the frame raises and lowers a separately powered horizontally movable guide means, which in turn is connected to the lever free end. Thus, the wheel is universally adjusted by rotating the cage, moving the frame forwardly or rearwardly within the cage, and swinging the free end of the lever arm upwardly and sideways.

    摘要: The coating of a conductor pattern on dielectric green sheets to a common edge thereof with stacking or superimpositioning together of a plurality of sheets to enclose the conductor pattern followed by sintering, with the edge side of the fired body having the exposed end terminations becoming the actual face of the body on which a semiconductor device is mounted in electrical circuit connection to respective ones of the common end terminations of the conductor runs. The conductor runs are returned through the body to the active face of the body to position the opposite or distal ends of the conductors thereat, in an increased spaced relationship of the distal conductor terminations. For external connection, terminal pins may be embedded in the fired body for connection at adjacent and to the distal conductor termination, with the pins projecting therefrom.
