ABSTRACT:
Disclosed is a system for testing serial communications electrical circuit boards which interfaces to a board being tested through a plurality of serial channels. The system contains a plurality of personality modules, each of which can interface directly to a channel. A personality module will perform level shifting, data encoding/decoding, line termination, and clock/framing extraction as needed for a particular serial protocol. The system also contains one or more reconfigurable bit processors which may be connected together in a building block fashion to perform low-level processing on serial data received from or sent to a personality module. One of a plurality of serial test sequencers receives or sends data from/to a reconfigurable bit processor; provides a user programmable apparatus to control the application and reception of test patterns to and from a channel; and interfaces to the user through a system controller.
