how to continue simulation without overwriting the raw file?

[tigrex]

there are cases that a simulation is killed.
raw file and log files produced..

in case i want to continue the simulation at the last point? (without overwriting the created raw file)
what should be the steps to this idea?

i read about the +checkpoint and +recover
i tried adding parameter cktperiod to my transient simulation to create recovery files (.ckpt extension)
::: my analysis statement : tran timesweep stop=100u errpreset=conservative ckptperiod=1
::: in my working directory
::: .spe ---> my stimulus file
::: .lis ---> my simulation log file

workingDirectory>ls
test1.spe test1.lis test1.raw test1.raw.timesweep.ckpt

::: the .ckpt file was produced because of the ckptperiod parameter
::: i tried to use recover

workingDirectory>spectre +recover test1.spe > test1.lis


::: but after the simulation, the raw is overwritten
and it started at the last checkpoint

want i want is that the simulation is continued from the present raw file
simply appending data to the killed simulation..

what i got is simply the solution at the start sweep of the simulation.
please help me

Re: how to continue simulation without overwriting the raw f

i will say the best solution is copy the psf/raw dir with another name psf_1 like that so i doest cause any problem and you still have the previous waveform's

No, this doesn't help.
What tigrex needs is to continue the simulation, not just to keep the old waveform.
