An apparatus comprising an integrated circuit and a logic portion. The integrated circuit may have a plurality of regions each (i) pre-diffused and configured to be metal-programmed and (ii) configured to connect the integrated circuit to a socket. The logic portion may be implemented on the integrated circuit. The plurality of metal programmable regions are each (i) independently programmable and (ii) located in one of said pre-diffused regions. Each of the metal programmable regions comprises (a) a regulator section configured to generate an operating voltage from a common supply voltage, (b) a logic section configured to implement integrated circuit functions and operate at the operating voltage, and (c) a level shifter configured to shift the operating voltage to an external voltage level.

A basic cell circuit architecture having plurality of cells with fixed transistors configurable for the formation of logic devices and single and 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 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 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.

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.
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.
