Gate array - Wikipedia
A gate array is an approach to the design and manufacture of application-specific integrated circuits (ASICs) using a prefabricated chip with components that are later interconnected into logic devices (e.g. NAND gates, flip-flops, etc.) according to custom order by adding metal interconnect layers in the factory. It was popular during the ...

2022年11月19日 · 门阵列(gate array)设计方法利用在布局中插入的金属层从而定义逻辑函数。 设计人员完成逻辑设计（如表达式）后，通过插入金属层将单元中的元件适当地连接起来形成逻辑门，然后将逻辑门适当地连接起来，从而实现逻辑网络。
Gate Array (GA) Design in ASICs - siliconvlsi
2023年9月7日 · Gate arrays are characterized by an array of predefined base cells that are interconnected to form specific logic functions. The designer’s role in gate array customization primarily involves defining masks for creating connections and contacts between these base cells.
In view of the fast prototyping capability, the gate array (GA) comes after the FPGA. Gate array is done with metal mask design and processing. The first phase, which is based on generic (standard) masks, results in an array of uncommitted transistors on each GA chip.
In this thesis, a methodology to implement large scale ECOs is presented. This method-ology aims to overcome the existing limitations of using the ECO algorithms by incor-porating conventional ASIC ow algorithms to perform an ECO. The methodology has been implemented using gate array type cells.
Gate-Array Layout † A gate-array (MPGAs) consists of transistors prefabricated on a wafer in the form of a regular 2-D array. † Initially the transistors in an array are not connected to one another. † In order to realize a circuit on a gate-array, metal connections must be placed using the usual process of masking (personalizing).

Gate Array Design. The gate array (GA) ranks second after the FPGA, in terms of fast prototyping capability. While user programming is important to the design implementation of the FPGA chip, metal mask design and processing is used for GA. Gate array implementation requires a two-step manufacturing process.

Computer-aided design tools are now making it possible to automate the entire layout process that follows the circuit design phase in VLSI design. This has mainly been made possible by the use of gate array and standard cell design styles, coupled with efficient software packages for automatic placement and routing.
