Abstract
An integrated circuit device such as a programmable integrated circuit may include interface circuits and associated identification circuits. The identification circuits may be coupled to shared mixer circuitry that performs a logic function on mixer input signals received from the identification circuits of that integrated circuit to produce a mixer output signal. Debug computing equipment may be used to test integrated circuits having mixer circuitry. The debug computing equipment may have interfaces that receive connections to interface circuits of the integrated circuits. The debug computing equipment may communicate with the mixer circuitry of the integrated circuits through each of the connected interface circuits to identify groups of interfaces that are connected to different devices. For each device, the debug computing equipment may select an interface from the corresponding group of interfaces and perform test debug operations over the selected interface.
