Abstract

Aiming at the low verification efficiency of the simulation platform built by traditional hardware description language, which is difficult to meet the problem of ultra large-scale chip verification, a simulation platform built based on UVM methodology is proposed. The functional verification of the USB device controller is completed by random test excitation with constraints, and the automated comparison mechanism can output the verification results in real time, which is convenient for problem location and debugging. Compared with the traditional verification, this method improves the verification efficiency by 30%, makes the verification results more comprehensive and reliable, and meets the verification requirements of digital chips.
