A SoC verification method and debugging tool for radio frequency signals

Abstract

The invention discloses a SOC verification method and a debugging tool for radio frequency signals. First, a radio frequency demodulation module and an FPGA interface are used to construct a debugging tool; secondly, the debugging tool is connected to an FPGA verification platform of the SOC; then, the control The RF demodulation module on the debugging tool receives the RF signal and converts it into a CVBS signal or TS stream, and outputs it to the FPGA verification platform through the FPGA interface; the FPGA verification platform uses the received CVBS signal or the TS stream to debug the SOC system verify. The invention uses a specially designed debugging tool to verify the FPGA verification platform, thereby improving the efficiency of SOC chip development and verification in the early stage and ensuring the authenticity of the verification. In addition, the function modules on the debugging tool and the verification platform can also be debugged through the test interface reserved on the debugging tool, which facilitates the debugging work.

Description

technical field [0001] The invention belongs to the technical field of debugging and verification of a single-chip system, and in particular relates to a verification method and a debugging tool for a system single-chip SOC for radio frequency signals. Background technique [0002] In the current TV receiving system, the video decoding main chip integrated with CPU is the core of the whole system. With the development of electronic design and manufacturing technology, integrated circuit design has developed from the integration of transistors to the integration of logic gates, and now to the integration of IP, that is, System-on-Chip (SOC) design technology. The use of SOC to design system circuits can effectively reduce the development cost of electronic / information system products, shorten the development cycle, and improve the competitiveness of products. Therefore, it is the most important product development method that will be generally adopted by the industry in the f...

Problems solved by technology

Due to the differences in circuits and the extension of wiring, there are often different interferences during verification, and due to the limitations of the complete machine product, it is not possible to flexibly adjust the corresponding parameter settings of the electronic tuner and demodulator, resulting in the inability to approach the real Validation results
