摘要： A basic cell circuit architecture having plurality of cells with fixed transistors configurable for the formation of logic devices and/or single/dual port memory devices within a structured ASIC is provided. Different configurations of ensuing integrated circuits are achieved by forming variable interconnect layers above the fixed structures. The circuit architecture can achieve interconnection of transistors within a single cell and/or across multiple cells. The interconnection can be configured to form basic logic gates as well as more complex digital and analog subsystems. In addition, each cell contains a layout of transistors that can be variably coupled to achieve a memory device, such as a SRAM device. By having the capability of forming either a logic circuit element, a memory device, or both, the circuit architecture is both memory-centric and logic-centric, and more fully adaptable to modern-day SoCs.

摘要： A method of reducing power rail transients on integrated circuits. The power rail transients are reduced by controlling clock skew in a manner which minimizes dI/dT current demands. The method provides that the phase of the clock to latches/flip flops is shifted in order to spread out the number of simultaneous switching elements. By controlling the number of simultaneous switching devices, a significant reduction in time rate of current demanded from the power rails can be achieved, thereby reducing the magnitude of VSS/VDD voltage transients due to parasitic inductances and resistances supplying power to the integrated circuit. Theoretically, the entire timing spread of the slack graph for clock skew can be used to control the number of simultaneous switching devices.
摘要翻译：一种降低集成电路电源轨瞬变的方法。通过以最小化dI / dT电流需求的方式控制时钟偏移来减少电源轨瞬变。该方法提供了锁存/触发器的时钟相位被移位以便展开同时开关元件的数量。通过控制同时开关装置的数量，可以实现从电源轨所需的电流的时间速度的显着降低，从而减小由寄生电感和向集成电路供电的电阻引起的VSS / VDD电压瞬变的幅度。理论上，用于时钟偏移的松弛图的整个定时扩展可用于控制同时开关器件的数量。

摘要： A method and apparatus are provided for placing cells in an integrated circuit layout pattern. A base layer layout pattern defines an array of base cell locations and base layer elements, wherein at least portions of some rows in the array are reserved for decoupling capacitor cells. Each decoupling capacitor cell has a width, which is greater than that of a single base cell location and which is abstracted from the base layer layout pattern. A cell library defines a plurality of cells, including a macro cell having open rows consistent with the rows in the base layer layout pattern that are reserved for the decoupling capacitor cells. The width of each decoupling capacitor cell is abstracted from the macro cell. Cells from the cell library, including the macro cell, are placed within a design layout pattern relative to the base layer layout pattern. An area consumed by the macro cell within the design layout pattern is independent of the width of the decoupling capacitor cells.

摘要： A method is provided for fabricating an integrated circuit having a logical function. The method includes fabricating first and second routing layer masks and a first via mask. The first routing layer mask includes power supply segments and signal segments. The second routing layer mask includes signal segments and filler segments, wherein the filler segments are located in unused areas of the second routing layer mask. The first via mask defines vias that electrically couple the filler segments to the power supply segments. If the logical function is changed after the masks have been fabricated, a second via mask is fabricated. The second via mask decouples a filler segment from the power supply segments and couples the filler segment to a signal segment defined by the first routing layer mask to implement the logical function change. The integrated circuit is then fabricated with the first and second routing layer masks and the second via mask.
