The invention relates to a wireless communication technology, in particular to a hardware platform device for verifying system-on-chips. The hardware platform device comprises a media access control upper unit, a media access control lower unit, a digital baseband verification unit and a management expansion interface unit, wherein the media access control upper unit is connected with a host machine, and is connected with the media access control lower unit through a high-speed mezzanine card (HSMC) connector; the media access control lower unit is connected with the media access control upper unit through the HSMC connector; the digital baseband verification unit is connected with the media access control lower unit, and provides an upstream interface and a downstream interface; and the management expansion interface unit is connected with the media access control upper unit. By the hardware platform device, functions of a media access control layer, a physical layer, an analog to digital(AD)/digital to analog (DA) front end and the like are conveniently realized; the shortcomings caused by independently debugging software or hardware are overcome; and software and hardware collaborative simulation verification is realized.
