Summary
Returns all objects associated with a from-to object whose Net , From Pad, and To Pad properties comply with the Query.
Syntax
InFromTo('Net_Name (From_Pad : To_Pad)') : Boolean/Boolean_String
Net_Name, From_Pad, and To_Pad are all strings; the only single quote characters (') used are those depicted above (immediately within the outermost pair of brackets).
Each of the From_Pad and To_Pad strings specifies the full name that a pad has to match; this consists of an initial substring which specifies the Name property of the pad's parent component (i.e. the component's Designator), followed by a substring that specifies the pad's own Name property (i.e. the pad's Designator). The format will therefore be 'ParentComponentDesignator-PadDesignator'.
Example Usage
InFromTo('VDD_XTAL (C13-2 : U1-8)')
InFromTo('VDD_XTAL (C13-2 : U1-8)') = True
InFromTo('VDD_XTAL (C13-2 : U1-8)') = 'True'
Returns all objects associated with a from-to object whose Net property is VDD_XTAL, From Pad property is C13-2, and To Pad property is U1-8. (As such, the From Pad has a Name property of 2, and its parent component object has a Name property of C13. Similarly, the To Pad has a Name property of 8, and its parent component object has a Name property of U1).
Tips
- The parent from-to objects are also returned.
