Adapter for simultaneous use of logic analyzer and in circuit emulator

摘要

Debugging and development of hardware and software for microprocessors make desirable use of commercially available logic analyzers and in circuit emulators. The probes of the former have heretofore comprised clips which have been clipped onto exposed contacts on the plug of an emulator probe, the pins of which have been fitted into sockets in a printed circuit board or the like to replace a removed microprocessor. The foregoing step has been difficult (in part because of space limitations when as many as 64 clips have been required), time consuming and subject to possible error. A combination plug socket is provided in accordance with this invention. The pins of the plug side of the latter fit into the socket in the board and are connected to wires leading to the logic analyzer with a buffer resistor network interposed. The pins of the plug of the emulator fit into the socket side of the plug/socket.
