Modularized semi-customized FPGA chip design method completed by means of automatic tool

Abstract

The invention relates to a modular semi-customized FPGA chip design method completed by an automatic tool, and belongs to the technical field of chip design. The method comprises the following steps: 1) completing a description file of a chip architecture; the description file needs to comprise process parameters, resource block distribution, time sequence constraint information and other to-be-customized overall architecture information; 2) analyzing the architecture file to generate a formatted integrated circuit netlist and a time sequence constraint file; 3) calling a resource block library file; 4) adding a customization unit; 5) performing comprehensive layout wiring; and 6) generating a board pattern. According to the method, on the basis of the expandability of the internal resources of the FPGA, designers can freely expand or cut the internal resources of the FPGA according to a specific application scene, the FPGA chip is rapidly customized, the chip design time is shortened, and the optimal area, power consumption and performance of a resource block are achieved while the development efficiency is improved.

Description

technical field [0001] The invention relates to a modular semi-custom FPGA chip design method completed by an automatic tool, belonging to the technical field of chip design. Background technique [0002] The field programmable gate array (FPGA) chip is mainly composed of programmable input and output units, configurable logic unit blocks, clock management modules, embedded RAM blocks, wiring resources, and embedded dedicated hard cores and other resources. For different application scenarios, the types and quantities of internal resources of the FPGA chip will be different. [0003] Driven by the demand for large-scale data processing applications, current FPGA chips play an increasingly important role in computing systems. In order to address the unprecedented processing power challenges faced by specific domain applications, FPGA chips can be domain-customized. However, the design and development of custom FPGA chips is a complex process that requires personnel with str...
