The Architecture of FDP FPGA Device

Abstract

A novel FuDan programmable(FDP) FPGA device architecture was presented. The new 3-LUT based logic cell could increase logic density about 11% comparing with a traditional 4-input LUT. The uniquely hierarchy programmable routing fabrics and effective switch box could optimize the routing wire segments and make it possible for different length to connect directly and efficiently. The FDP FPGA device contains 1,600 programmable logic cells, 160 programmable IO Blocks and 16 K bits dual port block RAM IP Core. It was fabricated with SMIC 0.18 mum Logic 1P6M Salicide 1.8 V/3.3 V process, its die size is 6.1times6.6 mm2, with the package of QFP208.
