How Are NLP Expressions Used during auCdl Netlisting?

Netlisting Properties (NLP) expressions provide support for user defined properties in auCDL netlisting. You can use different NLP expressions depending on your requirements. Details about each NLP expression is described below:

• NLP expression beginning with “[+” is equivalent to pPar in AEL expression. For example, if property “myprop” has value “[+subProp]”, it will appear in auCDL netlist as myProp = subProp. The netlister prints the value of subProp for the SUBCKT on which it is defined.
• NLP expression beginning with “[@” is equivalent to atPar in AEL expression. For example, if property “myprop” has value “[@subProp]”, it will appear in auCDL netlist as myProp = subProp.
• NLP expression beginning with “[~” is equivalent to iPar in AEL expression. For example, if property “myprop” has value “[~subProp:new value %: not found]” and subProp has a value of 10 for the instance being netlisted, it will be printed in the netlist as myProp = new value 10. However, if subProp is not defined at instance level, it will be printed in the netlist as myProp = not found.
