    In upf, we can specify a module to be in certain power domain when create that power domain with

    >create_power_domain PD1 -elements {U1/foo1}

    or add modules later with

    >add_domain_elements U1/PD1 -elements {U1/foo2}

    But upf spec is not clear if we can specify a signal to be in certain pwr domain with above commands.

    I am not sure if it is really needed. Can you share in what case you’d like to declare a signal to be in some pwr domain? Normally we declare modules and ports and that is good enough. Backend tool can understand a signal is from a module of some pwr domain to another module of another pwr domain. There is also low power static tool to check.
