    Spectre MDL newbie. How to use acnames/actimes with spectre mdl? Reply

     Hi,

    I am relatively new to spectre MDL and have a question that I have been unable to find any documentation about.

    Here is the problem. I have a main netlist which contains the following analyses:-

    tran1 tran stop=2m errpreset=conservative save=allpub infotimes=[0.5m 2m] infoname=traninfo actimes=[0.5m 2m] acnames=[ac1]
    traninfo info what=oppoint where=file file="%C:r.%A.dcinfo"
    ac1 ac start=1 stop=1e12


    The mdl control file consists of the following:-

    alias measurement tranrun
    {
    run tran1
    export real gate_volt = V(out)@1e-3
    export real gain=mag(ac1:V(out))@10
    }//endmeas
    run dc1
    run dcinfo
    run tranrun


    The problem is with the line
    export real gain=mag(ac1:V(out))@10

    where I need to access the ac magnitude of a node "out" at 10Hz. A lot of variations that I have tried dont work. From what the mdlref says, this is a supported analysis but I could not find any other documentation. Can you please help me?

    Thanks in advance,
    Saurabh

    Saurabh,

    MDL can't handle nested analyses like this - there's a CCR, 694625, on this specific problem with actimes/acnames.

    I suggest you contact customer support with your example and a duplicate CCR can be filed.

    Kind Regards,

    Andrew.
