Abstract

System and method for analyzing design elements in a CAD tool design. A configuration element generator encodes information in a configuration command to generate a configuration element associated with at least one of the design elements. A sequencer, coupled to the configuration element generator, tags the configuration element with a sequence number. A computer memory, coupled to the sequencer, stores the configuration element. A processor, coupled to the computer memory, applies, to the design element that is of interest, each stored said configuration element associated with the design element of interest, in an order indicated by the sequence number. A configuration element is an encoding of data comprising formatted information associated with a design.

Claims

1. A method for analyzing design elements in a CAD tool design comprising the steps of:

for each configuration command in a configuration file;

encoding information in the configuration command to generate a configuration element;

ordering the configuration element with a sequence number indicating the order in which the configuration command appeared in the configuration file; and

storing the configuration element in computer memory; and

for each said design element of interest;

applying each of the configuration elements stored in said computer memory to the design element of interest in an order indicated by the sequence number to analyze the design.

2. The method of claim 1, including the steps of:

storing the configuration element in a first list if the configuration element is a partial specifier;

storing the configuration element in a second list if the configuration element is a complete specifier;

evaluating each partial specifier in the first list to determine if the evaluated partial specifier matches the design element of interest;

retrieving the configuration element into a third list if the evaluated partial specifier matches the particular configuration element; and

retrieving, into the third list, each complete specifier in the second list that matches the particular configuration element.

3. The method of claim 2, including the step of discarding the third list from said computer memory after the configuration elements therein have been applied to the design element of interest.

4. The method of claim 2, wherein said complete specifier comprises a name of one of said design elements, and wherein said partial specifier comprises a regular expression, that, when evaluated, yields said name.

5. The method of claim 1, wherein the configuration element comprises design element information, and wherein the design element is selected from the group of design elements consisting of a transistor, a wire, a capacitor, a resistor, a diode, an operational amplifier, a logic gate, a hierarchical sub-design, and a power supply.

6. A method for analyzing design elements in a CAD tool design comprising the steps of:

for each configuration command in a configuration file;

encoding information in the configuration command to generate a configuration element;

ordering the configuration element with a sequence number indicating the order in which the configuration command appeared in the configuration file;

storing the configuration element in a first list if the configuration element is a partial specifier; and

storing the configuration element in a second list if the configuration element is a complete specifier;

for each said design element of interest;

evaluating each partial specifier in the first list to determine if the evaluated partial specifier matches the design element of interest;

retrieving the configuration element into a third list if the evaluated partial specifier matches the particular configuration element; and

retrieving, into the third list, each complete specifier in the second list that matches the particular configuration element;

applying each of the configuration elements in the third list to the design element of interest in an order indicated by the sequence number; and

discarding the third list from said computer memory after the configuration elements therein have been applied to the design element of interest.

7. The method of claim 6, wherein said complete specifier comprises a name of one of said design elements, and wherein said partial specifier comprises a regular expression, that, when evaluated, yields said name.

a processor coupled to said computer memory, for applying, to said design element that is of interest, each stored said configuration element associated with said design element of interest, in an order indicated by the sequence number.

9. The system of claim 8, wherein the configuration element generator comprises a controller for generating the configuration element by selecting said configuration command from a configuration file.

10. The system of claim 9, wherein said controller:

stores the configuration element in a first list if the configuration element is a partial specifier, and stores the configuration element in a second list if the configuration element is a complete specifier;

evaluates each partial specifier in the first list to determine if the evaluated partial specifier matches the design element of interest;

retrieves the configuration element into the third list if the evaluated partial specifier matches the particular configuration element; and

retrieves, into the third list, each complete specifier in the second list that matches the particular configuration element.

11. The method of claim 10, wherein said complete specifier comprises a name of one of said design elements, and wherein said partial specifier comprises a regular expression, that, when evaluated, yields said name.
