Abstract: This paper introduces a solution for functional verification of DDR-SDRAM controller. The solution, based on VMT, completes the writing & reading operations happened between DDR-SDRAM controller and DDR-SDRAM model. The compatibility with AHB 2.0 specification is also verified. Using VMT accelerates building the testbench and writing the tastcases. Fast convergence of functional verification is implemented by analyzing the auto-check results, simulation waveform and coverage report. The verification based on FPGA proves the feasibility of the solution.
