Abstract
A novel FPGA chip FDP2008 (Fudan Programmable Logic) has been designed and implemented with the SMIC 0.18 μm CMOS logic 1P6M process. The new design method means that the configurable logic block can be configured as distributed RAM and a shift register. A universal programmable routing circuit is also presented; by adopting offset lines, complementary hanged end-lines and MUX + Buffer routing switches, the whole FPGA chip is highly repeatable, and the signal delay is uniform and predictable over the total chip. A standard configuration interface SPI is added in the configuration circuit, and a group of highly sensitive amplifiers is used to magnify the read back data. FDP2008 contains 20 × 30 logic TILEs, 200 programmable IOBs and 10 × 4 kbit dual port block RAMs. The hardware software cooperation test shows that FDP2008 works correctly and efficiently.-
