Regular Expressions for Creating Pin Names

All fields in which you specify power, ground, output, analog, and clock pin names accept regular expressions. The pin name in question is formed from the subset of the label text that matches the regular expression you enter.

Consider the following examples:

• To create power pins only from labels that match the string VDD, specify the following power pin name regular expression:
  ^VDD$
  The ^ matches the beginning of a string; the $ matches the end of a string. Therefore, only strings containing the VDD match the regular expression.
• To create a pin name that is identical to a label text containing the string VDD anywhere, specify .*VDD.* as the regular expression.
  In regular expressions,.* matches any sequence of characters.
  
  Abstract Generator does not check the regular expression you enter against any syntax rules.
