    output pin connected to power/ground net Reply

    Hello,
    I was trying to place and route a design with SOC Encounter after power planning and synthesis.

    My earlier trials of place and route without power nets were going relatively smoothly. After synthesizing power plan, I started to get many (~40) messages like

    **WARN: (SOCDB-2078):   Output pin Y of instance x0 is connected to ground net n_2.
    **WARN: (SOCDB-2078):   Output pin Y of instance x1 is connected to ground net n_1.
    **WARN: (SOCDB-2078):   Output pin Y of instance x2 is connected to power net n_15.
    **WARN: (SOCDB-2078):   Output pin Y of instance x3 is connected to power net n_14.
    **WARN: (SOCDB-2078):   Output pin Y of instance x4 is connected to power net n_13.
    ...
    ...

    I was wondering if anyone has dealt with this warning? I cannot make any sense of it. Many thanks in advance.

    Update:
    In case anybody faces this problem, I was able to eliminate warnings by giving unique names to all power/gnd nets, such as n_pwr_1, n_gnd_2, instead of using the synthesizer-generated generic net names such as n_1, n_2.
