    Hi,

    I got a design which reuse the same subckt:

    //////////////////////////////////
    subckt BLOCK in out
    M1 ...
    M2 ...
    M3 ...
    ends BLOCK

    subckt TOP in out
    BLOCKA (in out) BLOCK
    BLOCKB (in out) BLOCK
    ends TOP

    I0 (in out) TOP
    ////////////////////////////////

    If I do:

    alterA alter sub=I0.BLOCKA.M1 param=... value=...


    Will it only alter M1 for BLOCKA or it will alter M1 for the BLOCK
    subckt thus affect both BLOCKA and BLOCKB?

    Thanks,

    JD

    If it only alter M1 for BLOCKA, and BLOCKB still use the orginal BLOCK
    subckt, is there a way to alter BLOCK subckt once, so all the BLOCK
    instances will be affected.

    Thanks

    I don't believe this is currently possible. You should contact customer support
    to ask for an enhancement. Currently only a single instance can be altered
    at a time.

    Regards,

    Andrew.
