how to save spectre simulation results to a single raw file？

Spectre has never saved into a single file by default. If you picked the output format to be nutbin or nutascii (e.g. passing -f nutbin or -format nutbin on the command line). Perhaps you were doing that before and not now?

Hi Andrew

Thanks for your reply.

i am certain that the older version of spectre will work. After all , we have been using the all along.

Old version:12.1.0.272

Execute command “spectre acce110653216.sp -r 11.raw”，the result is a single raw file. As shown below:

-rw-r--r-- 1 chris model 56230 Feb 17 18:21 11.raw  

New version :23.1.0.063

Execute command：“spectre acce110653216.sp –r 22.raw”, the result is a folder named 11.raw. As shown below:

drwxr-xr-x 2 chris model 4096 Feb 17 2025 22.raw

I ran an example with the same (over 12 year old) version of Spectre, using a SPICE netlist (just in case that made a difference), and it didn't - I still got the default PSF result (i.e. a directory).

My guess is that you have an option within the netlist which is setting the output format. Can you share the contents of acce110653216.sp? If you can't share the entire file, I'd still want to see any options or analysis statements within the file. 

Regards,

Andrew

HI Andrew

Due the confidentiality reasons, I can not share this file with you.

I run command "more acce110653216.sp"

The content of the first few lines is as follows：

//** Keysight Inc **//
simulator lang=spectre
svop options save=selected rawfmt=nutbin

parameters vds=2.0
parameters vgs=1.0
parameters vbs=0.0
