Registering Regular Expressions-Based Supply Nets

If you do not know the names of the nets that exist down the hierarchy, there are some naming conventions followed. Here are the steps to register the regular expressions-based supply nets.

1. Specify regular expressions for nets in the Power Nets or Ground Nets fields on the Supply Nets tab of the Power Manager Setup form.
   For example, if you add vdd as a regular expression, such as iovdd, avddd1, or any net name that contains this is considered as power net. Similarly, if GND is specified as a regular expression, names such as GNDA, GNDD, and so on, are considered as ground nets. Also, if [v][V], [d][D], and [d][D] are defined as regular expressions, all combinations are considered, such as vdd, VdD, VDD, Vdd, and so on.
2. Specify the registration information in the Pwell, Nwell, Deep Pwell, or Deep Nwell fields on the Supply Nets tab of the Power Manager Setup form.
3. Click OK.
   
   

Power Manager checks for the presence of the registered nets and identifies them as power or ground nets. These registered nets are used to create power domains.
