Comprising the following steps: collecting PCIe serial codes of all PCIe devices and analyzing the PCIe serial codes into parallel code streams; the method comprises the following steps of: unpacking a three-layer protocol on a parallel code stream according to a protocol specification to obtain three-layer transaction stream information which is divided into a physical layer, a data link layer and a transaction layer; constructing a network topology structure of all PCIe equipment according to the acquired transaction flow information; and establishing a visual panel based on a Tkinter module of Python, and carrying out visual processing on the constructed network topology structure to realize PCIe simulation data visualization.

Description

technical field [0001] The invention relates to the technical field of integrated circuit design verification, in particular to a PCIe simulation data visualization method, system, device and medium. Background technique [0002] With the advent of the era of big data, massive amounts of data need to be processed, and processors and memory banks must be upgraded accordingly. At the same time, the demand for bandwidth and speed of the bus is also getting higher and higher. The traditional parallel bus can only be upgraded in terms of clock frequency and bus bit width, but its bottleneck is getting bigger and bigger. Crosstalk between lines caused by high speed, clock and data timing requirements, etc. all limit the improvement of its throughput. At present, the bus protocols commonly used in the system are high-speed serial buses such as PCIe, USB, Sata, and RapidIO. PCIe belongs to high-speed serial point-to-point dual-channel high-bandwidth transmission. The connected devi...
