The invention relates to a PCIE verification method based on the UVM. The PCIE verification method is characterized in that the UVM and a system-level hardware descriptive language are adopted, a verification environment platform is set up through a high-level extensible interface bus behavior model, functional verification is implemented on a PCIE module, and the verification environment platform comprises a test case, a sequence generator, an AXI drive module, a PIPE drive module, an AXI monitoring module, a PIPE monitoring module, a PCIE reference model, a scoreboard and a functional coverage rate module. Due to the fact that the UVM is implemented, a stratified verification structure can be obtained, the PCIE with different types of configuration can be easily transplanted and verified, random data packet excitation can be generated through constraints, all instructions and addresses can be traversed, and the functional coverage rate module can also collect and monitor the coverage rate.
