Adding Properties to a Library, Cell, or View

You can add properties to a library, cell, or view from the Library/Cell/View Property Editor form that appears when you choose Edit – Properties.

To add properties:

1. On the Library/Cell/View Property Editor form, click Add.
   The Add Property form appears.
   
   
2. In the Name field, type a name for the property.
3. In the Type drop-down list, select from the set of available property types.
   The type you select determines the fields that appear on the Add Property form:
   • If you select int, float, or time from the Type field, the subsequent fields are Value, Minimum Value, and Maximum Value.
   • If you select string from the Type field, the subsequent fields are Value and Possible Choices.
   • If you select boolean, ILExpr, ILList, NLPExpr, netSet, fileName, or hierProp from the Type field, the subsequent field is Value.
4. Type appropriate values in the remaining field or fields that appear based on the Type you selected in the previous step.
   

   Type	Field	Valid Values
   int	Value Minimum Value Maximum Value.	Any integer value The values specified in the Minimum Value and Maximum Value fields define an inclusive range for a property value. The Value is the default value and must be in the specified range. You can specify infinity (no limit over 0), -infinity (no limit under 0), or leave the field blank to reflect no limit on the value.
   float	Value Minimum Value Maximum Value	Any floating-point value
   time	Value Minimum Value Maximum Value	Time and date values
   string	Value Possible Choices	Any string (no quotation marks) or no string Additional comma-separated list of strings (no quotation marks) or no strings You can force a double quotation mark to appear as part of a choice by typing a backslash in front of each quotation mark. For example: \"string\" If you leave the Value field blank, you must also leave the Possible Choices field blank; the result is that any string can be specified as a valid value for this property You may specify Value without specifying Possible Choices; the result is that Value is the default string and any other string can be specified as a valid value for this property If you specify strings in both the Value and the Possible Choices fields, the result is a a drop-down list containing the only valid values for the property with Value as the default selection You cannot leave the Value field blank and type a string in the Possible Choices field.
   boolean	Value	TRUE, true, t, yes, FALSE, false, nil, or no
   ILExpr	Value	SKILL expression
   ILList	Value	SKILL list
   NLPExpr	Value	Expression evaluated by the netlister substitution language
   netSet	Value
   fileName	Value	Any valid file name string
