Abstract
A method and apparatus for developing placement characteristics of a circuit design in conjunction with developing functional aspects of the circuit. In various embodiments, an application programming interface (API) is programmed in a hardware definition language (HDL). The API provides placement directives that can be called from the HDL code that defines functional characteristics of the circuit. The API can also be used in a testbench in order to analyze both the functional and physical placement characteristics of the design. Since the API is programmed in HDL, the placement generated during the implementation phase is the same as the placement analyzed during functional simulation.
