Abstract: Technologies for editing a circuit design implemented in a hardware description language are provided. A representation of a circuit design described by a syntactic description of the circuit is generated. Subsequently, a modification operation is carried out on the circuit design representation after which a modified syntactic description may be generated from the modified representation.

Abstract: A method and apparatus for recognizing a state machine in circuit design in a high-level IC description language. The present invention analyzes high-level IC description language code, such as VHDL and Verilog®, of an IC design and extracts description information corresponding to a state machine. The description information can be, for example, the high-level IC description language code corresponding to the state machine, a state diagram of the state machine, a state table for the state machine, or other representation of the state machine. In one embodiment, the present invention identifies a set of one or more processes as defined by VHDL “process” statements. By identifying one or more clocked processes, one or more transition processes, and one or more output processes, the present invention provides a state machine summary to describe the state machine identified in the high-level IC description language code.

Abstract: Briefly, the present invention analyzes high-level IC description language code, such as VHDL and Verilog, of an integrated circuit (IC) design and generates graphical representations of the IC design based on the code analyzed. The graphical representations can include one or more of the following: 1) a block diagram of functional blocks; 2) a state diagram of a state machine; and 3) a flow chart of an operation al flow of the IC. Graphical representations provide more understandable representations of circuits described by the high-level IC description language code than the code itself.
