Top down design of UHF RFID tag based on SystemC

Abstract

With the development of science and technology, the design of integrated circuit becomes more and more complex.In the design process, the division of hardware and software also produces more choices. In order to meet the complex design requirements for integrated circuits, the development and design of SystemC, which inherits the C + + extension library, came into being. SytemC can meet the requirements of hardware and software codesign, and can be quickly simulated and verified in the design process. In this paper, the communication protocol(ISO/IEC 18000-6C) is modeled and designed at a higher level. The protocol communication between interrogator and tag is realized by function call. For UHF RFID(Ultra High Frequency Radio Frequency Identification)communication protocol, from system level design to behavior level design, the top-down design of the protocol is realized, and the design of tag identification layer and baseband communication link layer is completed. Finally, the source code of this systemc is transformed into Verilog and other hardware description languages by using Vivado HLS synthesis software, and the software description of system level is synthesized into RTL code. This paper focuses on label baseband link encode_T module, after FM0 / Miller coding simulation of data "1001001001011001" in Microsoft Visual C++ 6.0, the waveform verification is completed in Modelsim, and it is transformed into RTL level circuit by Vivado HLS integrated software.
