Generation of an extracted timing model file
View Patent ↗A system, apparatus and method for generating extracted timing model files, such as macro library files, are disclosed. A user interface or data template is provided to an engineer that allows for the population of data within particular fields related to timing characteristics of an IP block, cell or core. Various types of data and fields may be provided into the user interface or data template. The location of relevant files, such as a cell or core netlist, may be provided within the template. Additionally, one or more modes may be selected by the user to define the manner in which the ETM file(s) are to be generated. An ETM file is automatically generated using the information provided in the data template.
1. A method for generating extracted timing model files, the method comprising:
providing a data template in which information describing timing characteristics of a core is entered by a user using a computer;
populating at least one field within the data template with information describing timing characteristics of the core based upon information received from the user via said computer;
identifying at least one mode of operation associated with the core, from a plurality of available modes of operation for the core, using at least one field within the data template, based upon information received from the user via said computer; and
automatically generating an extracted timing model file using the information within the data template and storing the extracted timing model file on a computer readable medium.
2. The method of claim 1 further comprising the step of providing at least one file location within the data template.
3. The method of claim 2 wherein the at least one file location includes an address of the core netlist.
4. The method of claim 2 wherein the at least one file location includes an address of an .spf file associated with the core.
5. The method of claim 1 wherein the extracted timing model file comprises a .lib file.
6. The method of claim 1 wherein the data template comprises a plurality of questions and a plurality of fields in which answers to the plurality of questions are entered.
7. The method of claim 6 wherein a field, within the plurality of fields, allows the user to provide information about the technology related to the core.
8. The method of claim 6 wherein a field, within the plurality of fields, allows the user to provide the location a core map file.
9. The method of claim 6 wherein a field, within the plurality of fields, allows the user to provide at least on clock frequency within the core.
10. The method of claim 1 wherein the at least one mode of operation includes a test mode for the core.
11. The method of claim 1 wherein the at least one mode of operation includes a functional mode for the core.
12. The method of claim 1 wherein at least one constraint check is performed during the automatic generation of the extracted timing model file.
13. The method of claim 1 wherein at least one constraint check is performed after the automatic generation of the extracted timing model file.
14. A computer program product embodied on a computer readable medium for creating an extracted timing model file, the computer program product comprising computer executable instructions for causing a computer to perform the steps of:
providing a data template into which information describing timing characteristics of a core is entered in response to a user input;
populating at least one field within the data template with information describing timing characteristics of the core based upon the user input;
identifying at least one mode of operation associated with the core, from a plurality of available modes of operation for the core, by populating at least one field within the data template, based upon the user input; and
automatically generating the extracted timing model file using the information within the data template.
15. The computer program product of claim 14 wherein the at least one mode of operation comprises a test mode for the core or a function mode for the core.
16. The computer program product of claim 14 wherein the extracted timing model file comprises a .lib file.
17. The computer program product of claim 14 further comprising identifying at least one file associated with the core by entering at least one file location in at least one field within the data template based upon the user input.
18. The computer program product of claim 17 wherein the at least one file location includes an address of the core netlist.
