Method and system for testing an Application Specific Integrated Circuit is provided. The system includes, a simulator that interfaces with a host computer emulation module; and a virtual interface driver ("VID") that interfaces with the host computer emulation module and a bus interface module, wherein the VID maps plural stimulus to the simulator via the bus interface module. The method includes, loading a bus functional module in an ASIC simulator; determining configuration of devices supported by a host emulation system; and mapping configuration information to the host emulation system, wherein a virtual interface driver maps the configuration information to the host emulation system.
