Navigating-SoC (System On Chip) simulating, verifying and debugging platform

Abstract

The invention discloses a navigating-SoC (System On Chip) simulating, verifying and debugging platform, which comprises a navigating-SoC verifying plate and a PC (Personal Computer) host-computer environment, wherein an RISC (Reduced Instruction Set Computer) processor and an FPGA (Field-Programmable Gate Array) are integrated onto the navigating-SoC verifying plate, and the PC host-computer environment is used for assisting the debugging and the analysis of a designer. A navigating IP (Internet Protocol) is realized on the FPGA, and the support for a hanging / operating mode is added. According to a hardware-hanging / operating state, a navigation-interrupting program is divided into a hardware-hanging period and a hardware-operating period, the introduction of intermediate-frequency data into the SoC verifying plate is finished through a UDP (User Datagram Protocol) / USB (Universal Serial Bus) protocol by a PC host computer at the hanging period, and debugging information is sequentially transmitted to the PC host computer by the SoC verifying plate. In the invention, the operating time of a code on the RISC processor is also accurately analyzed by utilizing a timer resource on the SoC verifying plate, and the real-time property of software and hardware can be analyzed. A PC host-computer end comprises a GUI (Graphical User Interface), a UDP / USB communication thread and a background database, so that a perfect verifying environment is provided for the designer.

Description

technical field [0001] The invention relates to the field of SoC (System On Chi, system on chip) verification and debugging, in particular to a device platform capable of emulating, verifying and debugging a navigation SoC chip. Background technique [0002] Global Navigation Satellite System (GNSS) has been widely used in various fields in the past few decades. At present, GNSS includes GPS of the United States, GLONASS of Russia, Compass (Beidou) of China and Galileo system of the European Union. In the civilian field, most mobile devices have navigation functions, which provide great convenience for people's travel. Many vehicles are equipped with GPS navigation equipment, which greatly simplifies the management of the transportation industry. In the military field, the navigation system is the top priority of modern warfare, and the core of these devices is the navigation chip. In the field of navigation chip design, there is a certain gap between domestic and foreign...
