The invention discloses a script-based establishment system and method for a functional verification platform. The system comprises a bus architecture information document module, an internal register and ram module, a chip initialization control document module and an automation script module. By using automation scripts, establishment and operation work of the verification platform is automatically completed. commands are tested based on a standard Avalon bus protocol design verification platform, and universal reading and writing testing of the designs based on an Avalon bus is achieved. Correct testing of specific storage modules is achieved by using information documents of the internal register and ram module. Configuration of initial verification environments for different designs is achieved by using chip initialization control documents. The method is easy to implement, the process is simple, efficient and stable, a development cycle of the establishment function verification platform for different Avalon bus based designs can be greatly shortened, and the function verification efficiency can be improved.
