Hardware software communication channel to support direct programming interface methods on fpga-based prototype platforms

A method comprising:

• encoding a direct programming interface (DPI) call from a behavioral model for transmission to a field programmable gate array (FPGA);
• dispatching the DPI call via an interconnect link;
• receiving the DPI call at the FPGA via the interconnect link;
• decoding the DPI call via a DPI call encoder within the FPGA;
• and
• performing a task specified by the DPI call via a hardware transactor implemented via the FPGA.

A system comprising:

• a memory device configured to store instructions;
• one or more processors coupled with the memory device, the one or more processors configured to execute the instructions;
• and
• a field-programmable gate array (FPGA) including hardware logic that is configurable to emulate functionality of a die of a multi-die SoC device to enable validation of a processor die coupled with the FPGA,
• wherein the hardware logic is configurable to implement a hardware transactor associated with a direct programming interface (DPI), the hardware transactor to perform a wire-level sequence of operations to interconnects of the processor die in response to a request received via a DPI export call, the DPI export call transmitted via the instructions executed by the one or more processors.
