A method and system for transaction-based verification of a design under test by a test bench that configures the DUT with at least one configuration including one or more configuration values. In one embodiment, the system comprises a modulation circuit portion for generating modulated FM signals. The rear swing link and the front swing link are selectively pivotable about the first and second pivots respectively to enable the mechanism to be selectively shifted between an upright position and a reclined position. An optical recording medium drive apparatus and a recording layer access method for the guide-layer separated optical recording medium are also provided. There are spaces between the taught lacings for easy ingress and egress and the taught lacings act to shield the occupants in the transfer device from inadvertent side impacted.
