Title: How to limit .raw file size in MDL?
Post by topquark on Jan 26^th, 2007, 2:41am

Hi Folks,
I've started using MDL for a lot of my measurements.
It's quite handy, offers a lot of features but I noticed it hogs my disk space very quickly(esp. when using 'foreach' loops)!

I traced it to the fact that the .raw file contains voltages at all nodes & currents through all elements!!
How can I choose specific nodes to be output like we do in OCEAN using-
saveOption( '..." )

I couldn't find any info about this in the user manual.
Anybody has a clue?

Regards,
gau

Gau,

The easiest way to accomplish this is to add the following to your options statement in the spectre netlist:
"save=nooutput". This is a relatively new feature, so it may or may not be available with your release.
An alternative method is to explicitly save only one signal in the netlist. That will still generate raw files
for that particular signal, but should reduce your output.

Hope this helps,

Scott,
Thanks for your reply-

I tried adding the statement "save=nooutput" in the netlist file(.scs) but it's not being recognized.
So, I tried commenting the line
saveOptions options save=all pwr=all currents=all

Now, the .raw file was reducedin size, just containing some node voltages and currents thru some elements.
But, how do I specify any particular node/element I need to be output?
Could you please show me the syntax in the above.

Thanks,
Gau

Solved!

I just specified the voltage nodes and current elements in the schematic, extracted the netlist in ADE
It appears as
save Vin C0:1 R8:1 Vout
saveOptions options save=selected pwr=none currents=selected

Now, even MDL simulations produce raw o/p with the selected nodes & elements.

Thanks Scott!
