The Calibre xRC tool, however, will extract and produce a PDB containing a net model consisting of several disjoint parasitic model fragments—a true representation of the actual drawn mwnual.

For a full mwnual and more information please click here. If no port text is available on a given net, the default mechanism for choosing the port location is used instead. Excludes any net, at any level of the hierarchy, that is not ported out and has a name containing the character string vdd.

For instance, this statement would exclude nvdd and vdds, no matter what level of the hierarchy they occur on. You shall maintain a record of the number and primary location of all copies of Software, including copies merged with other software, and shall make those records available to Mentor Graphics upon request.

Excludes any name in the top level namespace that has the character string vdd anywhere within it. Upon completion of your evaluation and testing, you will send to Mentor Graphics a written evaluation of the Beta Code, including its strengths, weaknesses and recommended improvements.

This will create a gds file for your layout. Excluding Nets — eliminates named nets from extraction and, consequently, the toolproduced netlist. If no value is specified, the tool ignores values of zero or less, and normally reduces the cluster into one via resistor.

The Calibre xRC tool reports degenerate nets in the Formatter transcript. How You Use the Tool. Via Reduction Example Initial via the tool finds value Resultant via cluster The tool uses capibre for determining the distance between adjacent vias using the following method: Figure shows an example invocation for the Calibre xRC Mabual. Therefore, it is recommended calubre you do not use this method to specify the connection of more than two layers unless it is absolutely necessary.

Mentor Graphics has no liability to you if infringement is based upon: Based on the text the rule check is that the OD or DOD layer has a density across the full chip of at least A site is calinre to a one-half mile meter radius.

You must change LVS command file by yourself. Descending into the xcell without connecting to any device within the xcell. However, when multiple layers are involved, the optimum hierarchical structure could vary from layer to layer. The net represents a valid connection. Before invoking the Calibre xRC tool, set this environment variable in the shell you will operate the Calibre xRC tool with.

It is possible the foundry has reasons for wanting you t. When you use this statement, you must list the nets by name you want excluded from the extraction run.

Performing Gate-Level Parasitic Extraction — contains concepts and usage procedures for using the Calibre xRC tool for gate-level parasitic extraction. For more information on performing find and search operations, refer to Using Mentor Graphics Documentation with Acrobat Reader.

Standard output formats are generated from: For example, you would set this environment variable in a C shell using the following syntax: Save the modified file as “layout. This argument generates netlists and reports from parasitic data generated during selected and flat extraction. Mentor Graphics will have exclusive rights, title and interest in all such property.

Software Problems, Hints and Reviews:: Additionally, you can perform specific parasitic extraction operations with these statements, for example reduction and thresholds. Configuring and Licensing Calibre Tools — contains information on system configuration and licensing information for the Calibre verification, MDP, RET, and parasitic extraction toolsets. The Calibre xRC Formatter produces this summary in the formatter log, normally fmt.

You must include any cell you identify with this statement in the xcell list. These files contain instances of the parasitic models and describes the net and any pins or ports the net connects to. Note The tool supports wildcards in the net name only, not in the path. By default, each PDB contains four segments, each holding up to 2. For example, the area and perimeter calculation might lea.

If the check catches anything, the report will show the text after the. Extracting Connectivity and Intentional Devices. Variable for Combining Resistors into a Single Resistor. Refer to Configuring and Licensing Calibre Tools for more information on this option. Use the following few lines to fix it.
