    • A method for reducing a surface area of a pad limited semiconductor die layout includes choosing an outer die pad row from a group of outer die pad rows on the semiconductor die, each of the outer die pad rows being adjacent an edge of the semiconductor die. Next, the method performs selecting, from the outer die pad row, a common die pad group with die pads that are arranged to be electrically connected to an external connection pad. The method then performs repositioning a subgroup of the common die pad group on an inner die pad row, the inner pad row being adjacent the outer die pad row. After he repositioning there is performed a step of adjusting positions of at least some of the remaining pads in the outer die pad row thereby reducing an overall length of the outer die pad row. The method then provides for repeating the above steps until the surface area of a pad limited semiconductor die cannot be reduced any further by the step of adjusting positions or until every common die pad group, on every one of the outer die pad rows, has been selected by the selecting step.
    • 一种用于减小焊盘限制半导体管芯布局的表面积的方法包括从半导体管芯上的一组外管芯焊盘行中选择外管芯焊盘行,每个外管芯焊盘排与半导体管芯的边缘相邻。 接下来,该方法执行从外管芯焊盘行中选择配置为电连接到外部连接焊盘的管芯焊盘的公共管芯焊盘组。 然后,该方法执行将内部焊盘排上的公共管芯焊盘组的子组重新定位,内部焊盘排与外部管芯焊盘排相邻。 在重新定位之后,执行调整外部管芯焊盘列中的至少一些剩余焊盘的位置的步骤,从而减小外部管芯焊盘排的总长度。 该方法然后提供重复上述步骤,直到通过调整位置的步骤不再进一步减小衬垫限制半导体管芯的表面积,或者直到在每个外管芯焊盘排上的每个公共管芯焊盘组已被 通过选择步骤选择。

    • A semiconductor die has rows of bond pads along the edges of a major surface. The corners of the die are designated as keep out areas, with design layout rules prohibiting a probe-able bond pad from being placed in the keep out areas so that a minimum distance may be maintained between distal ends of adjacent rows of bond pads (i.e., bond pads along adjacent edges). The bond pads of each row have IO pad areas that are aligned with each other and IO probe areas that are aligned with each other. A generally L-shaped bond pad includes a first, vertical part that extends inwardly from an edge of the semiconductor die and a second, horizontal part connected to the vertical part. The L-shaped bond pad may be placed between a last bond pad in a row and a corner keep out area, and the second part of the L-shaped bond pad extends into the corner keep out area. The first part has an IO pad area that is in alignment with the IO pad areas of the other bond pads in the same row, and the second part has an IO probe area that is in alignment with the IO probe areas of the bond pads in the adjacent row. The L-shaped bond pad does not violate design rules even though a part of the pad extends into the corner keep out area.

    • A clock signal generator provides a gated clock signal GCLK to trigger operation of dual-edge triggered circuits. A first detector generates, while a clock gating signal /EN is asserted, a first detector output signal that is asserted or de-asserted as a function of disjunction or conjunction respectively of the values that an input clock signal CLK and the gated clock signal GCLK had when the clock gating signal /EN transitioned. A second detector generates, while the clock gating signal /EN is de-asserted, as the value of the gated clock signal GCLK, the value CLK or its complement /CLK as a function of the first detector output signal. When the clock gating signal /EN is asserted, the second detector maintains the value that the gated clock signal GCLK had when the clock gating signal /EN transitioned from de-asserted to asserted.
