PCI-E protocol signal generation device and method

The invention discloses a PCI-E protocol signal generation device and method. The device comprises a PCI-E data stream generation module and a high-speed digital signal conditioning module, the PCI-E data stream generation module is used for simulating and generating a PCI-E data stream according to the content of a data packet set by a user, and encoding and sending a data link layer data packet, a physical layer data packet and a transaction layer data packet in the PCI-E data stream through GTX; and the high-speed digital signal conditioning module is used for carrying out signal conditioning on the PCI-E data stream and outputting the PCI-E data stream through the signal output interface. According to the invention, a 5Gbps high-speed serial data stream conforming to the PCIE-2.0 protocol specification can be sent, and PCI-E data packet types covering all key information fields in the PCI-E protocol specification can be freely selected and automatically assembled; the device has relatively high reliabilit
