In　this　paper,　we　use　Python　script　to　read　the　function　detailed　description　documents　of　CAN-FD　IP,　extract　the　required　information　according　to　the　main　keywords　and　other　information,　and　automatically　generate　the　qualified　System　Verilog　constrained　randomized　register　configuration　stimulator.　The　simulation　results　show　that　the　stimulator　can　meet　the　design　requirements　for　the　configuration　of　excitation,　and　can　effectively　improve　the　design　efficiency　of　the　verification　platform.　©　2020　IEEE.
