Abstract
A method for circuit design automation includes appending a non-synthesizable input having a unique identifier to HDL code that specifies a physical input of the circuit. For the physical components in the circuit to which a signal from the physical input is to propagate, corresponding non-synthesizable components are appended, having respective identifiers assigned responsively to the unique identifier of the non-synthesizable input, to the HDL code that specifies the physical components. The design is verified by simulating operation of the circuit using the HDL code, including both the physical and non-synthesizable inputs and components. After verifying the design, a netlist synthesis tool automatically generates a netlist of the circuit including the physical inputs and components while omitting the non-synthesizable inputs and components.
