Abstract
An diagnostic interface system for a programmable logic system is disclosed. The diagnostic interface system provides an efficient and flexible mechanism for accessing internal nodes of programmable logic devices (PLDs) to facilitate debugging and troubleshooting of the programmable logic system. The interface system includes a diagnostic data bus connecting external I/O pins to various diagnostic data and address registers that connect to the internal circuitry of a PLD. A diagnostics controller controls the various diagnostic resources in response to user supplied control data.
