When you set this variable to ON, the Formatter does not create new instance names for smashed devices. Mentor Graphics Calibre Manual. Variable for Enabling Arbitrary Output Mapping.

You must include any cell you identify with this statement in the xcell list. If your circuit is not working properly, after all possible logic checks, then there can be a layout error – a short between nets. Contacting Mentor Graphics SupportCenter Customer Support is available to any customer who has purchased technical support.

You must regenerate PHDBs if they become inconsistent with a current run; this can occur if you alter the rule file. You activate this functionality using a new environment variable you specify before creating the PDB with the Calibre xRC tool. Waiver of terms or excuse of breach must be in writing and shall not constitute subsequent consent, waiver or excuse.

Using Port Names for Net Names. How to tell which layers are base layers: Precision is ratio of database units to user units.

In general, those cells that contain the device level layers tend to be the most repeated structures, and upper level metal layers tend to form unique structures.

Order SVRF rule files are compiled before processing.

If you supply an empty xcell list, or if none of the msnual in the provided xcell list are found in the layout, the Calibre xRC tool will issue the following warning message at the conclusion of the Parasitic Database PDB stage: Parasitic Database PDB generation. You shall take appropriate action to protect the confidentiality of Software and ensure that any person permitted access ,anual Software does not disclose it or use it except as permitted by this Agreement.

The PDB stores the parasitic models for each extracted net.

Consequently, the tool extracts no parasitic devices for this partial net. Excluding Named Nets from Extraction. Variable for Limiting Via Reduction. You may not, however, redefine original layers. The Calibre xRC tool outputs netlists containing parasitic models, which are the extracted capacitance and resistance values associated with each extracted net.

For any Software under this Agreement licensed by Mentor Graphics from Microsoft or other licensors, Microsoft or the applicable licensor is a third party beneficiary of this Agreement with the right to enforce calibrre obligations set forth herein. In general, you use net exclusion for excluding power and ground nets from extraction.

Refer to Configuring and Licensing Calibre Tools for more information on this option. The syntax is documented in the calibre Verification User’s manualpart of the calibre documentation. Netlist Creation Format netlists—Using the Calibre xRC Formatter, the tool creates a netlist from the extracted electrical models in line with your specifications.

Consequently, you must have generated PDBs before using the Formatter. For example, the area and perimeter manjal might lea. For example, in a C-shell you would disable via reduction using the following syntax: Files the Formatter Produces. Consequently, this will create problems for post-extraction simulation because there is no physical rxc between these net fragments.

If the distance between any two adjacent vias is less than value, then the tool groups the adjacent vias together into a single via cluster. You can also specify where in the hierarchy to search for a matching net name. A site is restricted to a one-half mile meter radius.

That’s not an error, that’s a design rule check. This file contains the parasitic models. Chapter 1 Getting Started. Excludes any net, at any level of the hierarchy, that is not ported out and has a name containing the character string vdd.

Hi, calibre LVS shows I should not use design layer for pin text. You must enclose the string within quotation marks. Required files when you use Source Name Extraction. Floating Nets and the Formatter.

Figure shows manul 3-step command line invocations you must use when performing hierarchical extraction and netlist creation. It removes leading Xs from instance names. You will contact Mentor Graphics periodically during your use of mxnual Beta Code to discuss any malfunctions or suggested improvements.

Government or a U. The Calibre xRC tool reports degenerate nets in the Formatter transcript. The un-annotated layout net name could overwrite a legitimate source name with the same name.

In the new window, click on Rules. Setting a Limit for Via Reduction Table C-8 lists the environment variable you can use for specifying a limit for via reduction. Government subcontractor is subject to the restrictions set forth in the license agreement provided with the software pursuant to DFARS
