Abstract: A method and system for debugging using replicated logic and trigger logic is described. A representation of a circuit is compiled. One or more signals are selected for triggering and trigger logic is inserted into the circuit. A portion of the circuit is selected for replication. The selected portion of the circuit is replicated and delay logic is inserted to delay the inputs into the replicated portion of the circuit. The representation of the circuit is recompiled and programmed into a hardware device. A debugger may then be invoked. One or more of the triggering signals are selected. For each selected triggering signal, one or more states are selected to setup a trigger condition. The hardware device may then be run. The replicated portion of the circuit will be paused when the trigger condition occurs. The states of registers in the replicated portion of the circuit and the sequence of steps that led to the trigger condition may then be recorded.

Abstract: A multiport connector which includes a housing having at least two aligned compartments, each compartment being structured and arranged to receive respective plugs. A multilayer printed wiring board separates the two compartments, the printed wiring board having circuit patterns on opposite sides of opposed non-conductive layers and a metal shielding layer intermediate the non-conductive layers. A first plurality of conductive contact fingers is disposed in one of the compartments, the first plurality of fingers having first portions for making electrical contact with one of the plugs and second portions for making contact with the circuit pattern on one of the non-conductive layers of the multilayer printed wiring board.
