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

 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
