How to save Spectre tran results over just a specific period in a simulation

$

Hello,

I am running a spectre simulation from the command line and, as my simulation is large and extracted, I'd like just to save the tran results over a certain period. Not for the whole simulation.

My current command is

spectre ++aps +multithread -f fsdb VO15A_SERDES_TOP.sp -o /home/suppdm3/ANSYS/VO15A_SERDES_TOP

I haven't been able to find the option that I need to just specify say from "10ns to 20ns" for my simulation.

The call within my spectre.scs file is

tran tran stop=25n write="spectre.ic" writefinal="spectre.fc" \
    annotate=status maxiters=5

I think this must be a pretty easy option to define but I haven't found the right syntax.

Thanks for the help,

Matthew Cordrey-Gale
