Method and apparatus for interfacing between a high-level modeling system and a hardware description language (HDL) co-simulation engine. A plurality of HDL co-simulation engine libraries are queried as to the capabilities of the engines. A co-simulation engine is selected based on the capabilities, and an instance of the engine is created. The selected co-simulation engine is configured, input logic vectors are provided to the selected HDL co-simulation engine, and the co-simulation engine is executed accordingly.
