viaParamCalcMode

layout viaParamCalcMode cyclic { "minRulesAndViaDef" | "minRules" | "viaDefDefaults"| "minRuleEnclosures" | "viaDefEnclosures" }

Description

Lets you reset the values in the form to the technology database values if you want to revert from the manually updated parameter values to the defaults. When you first open the Create Via form, the via parameter values are calculated based on the Via Parameters Calculation Mode setting in the Create Via section in the Layout Editor Options Form.

• minRulesAndViaDef: Default. All the via parameter fields, such as the number of cut rows and columns, cut sizes, spacing, and enclosures, are reset to the minimum rule or the viaDef default values, whichever is greater.
• minRules: All the via parameter fields are reset to the minimum rule values. ViaDef defaults are not checked. Therefore, the calculated values can be less than the viaDef defaults. For example, if the minExtensionDistance rule is 0.05 and the default enclosure in viaDef is 0.1, 0.05 is used as the enclosure value in the Create Via form. The viaDef default enclosure value is ignored.
• minRuleEnclosures: Minimum rules are used to calculate only the enclosure field values. Values in the other fields are not reset.
• viaDefDefaults: All the via parameter fields are reset to the viaDef defaults. Minimum rules are not checked.
• viaDefDefaultsEnclosures: ViaDef defaults are used to calculate only the enclosure field values. Values in the other fields are not reset.
