A kind of fpga chip wiring method

Abstract

The invention relates to an FPGA chip wiring method, the method comprising: performing FPGA chip layout and obtaining the coordinates of each unit layout of the chip; according to the wiring mode of the FPGA chip, obtaining pre-stored wiring coding information corresponding to the mode; according to the layout of each unit The final coordinates determine the code corresponding to the unit, and then perform wiring pruning for each unit according to the wiring code information. The invention obtains the wiring coding information of the wiring pattern in the FPGA chip, and then performs reasonable pruning in the actual wiring process according to the pre-stored wiring coding information, thereby increasing the wiring speed and reducing the time delay.

Description

Technical field[0001]The present invention relates to the field of integrated circuit design in the field of microelectronics, particularly an FPGA chip wiring method.Background technique[0002]FPGA is a logic device with enriching hardware resources, powerful parallel processing capabilities, and flexible and heavy configurable. These features have enabled FPGA to have more and more widely used in many fields such as data processing, communication, and networks.[0003]Currently, in the Field Programmable Gate Array, FPGA applications, the integrated circuit requires a programmable or configurable interconnect network, and the logic gate is connected to each other by a configurable interconnection network. FPGAs that act as a core part of a stand-alone chip or system have been widely used in a large number of microelectronic devices. The definition of the logic door of a broad FPGA, not only simple and non-door, also refers to a logic unit (LE, Logic Element) having a combination logi...
