Claim 8:
9. A testing platform, configured to test a USB integrated circuit to be tested, the testing platform comprising:
a testing machine, configured to generate at least one test pattern; and
a USB integrated circuit, coupled to the testing machine to receive a first downstream signal conforming to USB4 V2 specification, wherein the first downstream signal comprises the at least one test pattern, the testing machine is further coupled to the USB integrated circuit to be tested to provide a second downstream signal conforming to USB4 V1 specification, the at least one test pattern generated by the testing machine is transmitted to the USB integrated circuit to be tested through the USB integrated circuit, and the USB integrated circuit comprises:
a first USB port physical layer circuit, configured to transmit a differential signal between the USB integrated circuit and the testing machine;
a first lane adapter;
a routing circuit, coupled to the first USB port physical layer circuit and the first lane adapter, wherein when the USB integrated circuit operates in a testing mode, the routing circuit electrically connects the first lane adapter to the first USB port physical layer circuit; and
a USB transport layer circuit, coupled to the first lane adapter.
