Placeholder-based design flow for creating circuit designs for integrated circuits

摘要

Within a system comprising a processor and a memory, a method of creating a circuit design for implementation within an integrated circuit can include inserting a placeholder block into the circuit design, wherein the circuit design includes a circuit block comprising circuitry and a circuit block interface, and wherein the placeholder block is devoid of circuitry and, responsive to receiving a user input specifying a coupling between the placeholder block and the circuit block, automatically determining a plurality of attributes of the circuit block interface. The method can include automatically generating, according to the attributes and by the processor, a placeholder interface within the placeholder block, wherein the placeholder interface is complementary to the circuit block interface. The placeholder block can be stored within the memory.
