Abstract
A test device and method with built-in self-test logic and a communication device. The test device includes at least one generator and at least one checker which are disposed between a physical layer and a medium access control layer. The at least one generator is configured to generate a protocol pattern to form a data path between the physical layer and the medium access control layer, and generate different pseudo random bit sequence patterns in the data path. The at least one checker is configured to test a data stream in the physical layer and/or the medium access control layer according to the pseudo random bit sequence patterns, thereby locating a fault position.
