A method for conducting bus arbitration in a hardware tester system comprising a single master controller and a multi-master controller comprises configuring the single master controller with arbitration logic operable to communicate on a bus in the hardware tester system using a same arbitration scheme as the multi-master controller, wherein the single master controller and the multi-master controller are connected to the bus. Further, responsive to a determination by the arbitration logic that the multi-master controller controls the bus, the method comprises withdrawing the single master controller from attempting to control the bus.
