Abstract
A debug system generates hardware elements from normally non-synthesizable code elements for placement on an FPGA device for used in electronic design automation (EDA). The FPGA device (Behavior Processor) operates to execute in hardware code constructs previously executed in software. When some condition is satisfied (e.g. If . . . then . . . else loop) requiring intervention, the Behavior Processor works with an Xtrigger device to send a callback signal to the workstation for immediate response. A memory block from a logic device is mapped to a memory device in a re-configurable hardware unit using a memory mapping system including a conductive connector driver, a memory block interface, and evaluation logic in each logic device, the connector driver, the interface, and the connector controller, the evaluation logic providing control signals used to evaluate data in the hardware model and to control write/read memory access between the logic device and the memory device via the driver and interface.
