High-bandwidth extendable complex logic verification system based on double FPGA (Field- Programmable Gate Array) chips

The invention provides a high-bandwidth extendable complex logic verification system based on double FPGA chips. Corresponding FPGA interconnection lines are used for connecting a PLB (Processor Local Bus) and an AXI (Automatic X-ray Inspection) bus in a FPGA chip to achieve data exchange with another FPGA chip, and providing control and arbitration of data stream between two FPGA chips through eight data sets; an extension interface module is used for providing interactions among two FPGA chips and an external functional module; an high-speed IO (Input/Output) channel is used for providing interactions among two FPGA chips and a PC (Personal Computer) machine; a configuration module is used for storing configuration codes and writing the configuration codes in two FPGA chips, respectively. According to the high-bandwidth extendable complex logic verification system based on double FPGA chips, a multi-FPGA-chip system is utilized to the user in a simple and configurable manner, and the system has higher performance; a FPGA board can be further connected with external devices through the extension interface module and realize multi-board connection through the extension interface module, the interference among multiple structures is less, and multiple selections are provided to the user.
