System-on-chip bus behavior detection method and apparatus

Abstract

An embodiment of the invention discloses a system-on-chip (SoC) bus behavior detection method. The method comprises the steps of receiving an SoC advanced extensible interface (AXI) bus signal; performing at least one of the following operations based on the AXI bus signal: capturing AXI bus channel data, and performing statistics on bus transmission parameters during AXI bus data transmission; and / or, receiving an AXI consistency extensible (ACE) bus signal in the SoC bus signal; and capturing ACE bus channel data based on the received ACE bus signal. An embodiment of the invention furthermore discloses an SoC bus behavior detection apparatus.

Description

technical field [0001] The present invention relates to the field of system on chip (System on Chip, SoC), in particular to a SoC bus behavior detection method and device. Background technique [0002] The current SoC chip is running faster and faster, and the main frequency of its processor has reached more than 2GHz. Therefore, it is impossible to capture the instantaneous signal by the test machine alone, and it is impossible to go deep into the chip to capture the bus signal. This requires a monitoring module. Embedded into the chip to capture bus signals in real time. [0003] However, existing monitoring modules such as SonicsMT and FlexNoC monitoring modules can only capture certain signals of the Advanced Extensible Interface (AXI) bus, specifically, existing monitoring modules can only capture The AXI bus address and commands are captured, but the AXI bus data cannot be captured; in short, the existing monitoring module has a single function and cannot meet the div...
