Abstract

The invention provides an EDA (Electronic Design Automation) hardware acceleration method and system based on a Banyan network and a multi-FPGA (Field Programmable Gate Array) structure, which comprises the following steps of: combining EDA algorithm acceleration and simulation acceleration in one system, starting a top EDA algorithm to control the sending and receiving of data when EDA algorithm acceleration is carried out, and carrying out EDA simulation acceleration according to a to-be-tested design structure designed by a user and simulation data input by the user when the EDA simulation acceleration is carried out; while using a multi-channel SCE-MI interface for software and hardware data collaboration, and using a Banyan network for achieving data exchange of multiple FPGAs; and finally, returning the accelerated data for processing, comparing simulation data with verification data to verify a simulation result, or returning operation result data to external EDA software. An algorithm and simulation are accelerated in a software and hardware cooperation mode, EDA algorithm acceleration and simulation acceleration are combined, a multi-channel PIPE type SCE-MI standard protocol interface is adopted, universality is achieved, meanwhile, a Banoan network is applied to multi-FPGA data exchange, data exchange delay is reduced, and the system is simple in implementation structure and efficient in function.

Description

technical field [0001] The invention relates to the technical field of EDA hardware acceleration, in particular to an EDA hardware acceleration method and system based on a Banyan network and a multi-FPGA structure. Background technique [0002] With the continuous development of the IC design industry and the continuous progress of ultra-large-scale IC process technology, the scale and complexity of IC design have doubled, which requires the computing power of EDA software to process simulation, synthesis, layout and wiring, verification and other processes. greatly increase. The calculation process of these EDA software often occupies a large amount of design time. As a kind of computing-intensive high-speed computing device with flexible configuration, FPGA has certain advantages when dealing with large-scale data computing and circuit simulation, and the proposal of multi-FPGA system is undoubtedly the icing on the cake. [0003] In a multi-FPGA system, the implementat...
