摘要： A disclosed memory, such as a random access memory (RAM) has multiple banks including a first bank and a second bank each having multiple latch cells configured to store data. The first bank has a first bit line, and the second bank has a second bit line. A first tri-state buffer has an input node coupled to the first bit line, an enable node coupled to receive a first enable signal, and an output node coupled to a tri-state bit line. A second tri-state buffer has an input node coupled to the second bit line, an enable node coupled to receive a second enable signal, and an output node coupled to the tri-state bit line. Enable signal generation logic uses a portion of an address signal to generate the first and second enable signals such that the first and second enable signals are not in an active state simultaneously. Avoiding concurrent activity of the enable signals eliminates contention on the tri-state output bit lines, and thereby prevents the mutually coupled tri-state bit lines output from the first and second tri-state buffers from being active at the same time. Placing a delay between activity minimizes contention on the mutually coupled, buffered bit line.

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： 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： Base platforms customizable into ICs are designed by identifying a plurality of macros for placement on the platform, each macro being defined in part by a plurality of elements that perform respective functions of the macro. Identical elements in a plurality of macros are identified, and a common element is placed on the platform for an identical element of at least two macros. All other elements of the macros are placed at locations on the platform relative to the common element as to satisfy macro placement rules for each macro. Identical elements can be identified by identifying similar elements in a plurality of macros, and creating a common element generic to the similar elements. The user designs a metalization layer to select macros and configure common elements to the selected macros.
