Abstract

The present invention provides a power supply structure of a CPLD logic unit array, comprising: a grid of power metal wires and two LDO circuits, and the two LDO circuits have the same circuit structure and device parameters, wherein the grid of power metal wires There is a distribution structure corresponding to the CPLD logic cell array, which is used to form the power supply current path of the CPLD logic cell array; two described LDO circuits are used to provide the operating voltage of the CPLD logic cell array, each of the The output terminals of the LDO circuit are respectively connected to one of the left and right sides of the power supply metal line grid, so as to supply power to the CPLD logic cell array from the left and right sides simultaneously. The invention can overcome the problem of uneven power supply voltage distribution at different positions of the CPLD logic unit array.

Description

Technical field [0001] The present invention relates to the field of CPLD technology, and more particularly to a power supply structure of a CPLD logic unit array. Background technique [0002] The CPLD is a referusion of complex programmable logic devices. It is an integrated circuit that can be designed according to the requirements of its own design, and has a wide range of application prospects in the switch and Internet communication. [0003] The logic unit array inside the CPLD is distributed, and the power trace inside the CPLD is also distributed. At present, the mode of power supply commonly used in CPLD is to power the CPLD logic unit array, but this power supply mode, the power supply voltage has a relatively large difference, especially from the power supply inlet to the most The distal end will produce a very large pressure drop, which results in a low power supply voltage of the farthest end of the power supply inlet, thereby affecting the performance of the CPLD. ...
