Xilinx (Sai Lingsi) is the world's leading provider of programmable logic integrity solutions. Xilinx develops, manufactures and markets a wide range of advanced integrated circuits, software design tools, and IP (Intellectual, Property) cores as predefined system level functions. The client uses the automated software tools of the Xilinx and its partners and the IP check device to program to perform specific logical operations. Xilinx pioneered the innovative technology of field programmable logic array (FPGA), and introduced commercial products for the first time in 1985. Right now, Xilinx meets more than half of the world's demand for FPGA products. The Xilinx product line also includes complex programmable logic devices (CPLD). In some control applications, CPLD is usually faster than FPGA, but provides less logical resources. Xilinx programmable logic solutions shorten the time for electronic device manufacturers to develop products, and accelerate the speed of products coming on the market, thus reducing the risk of manufacturers. In contrast to traditional methods such as fixed logic gate arrays, Xilinx programmable devices allow customers to design and validate their circuits more quickly. Moreover, since Xilinx devices are standard components that require programming only, customers do not need to wait for samples or pay huge costs as they do with fixed logic chips.
