A technical q. about HSpice output files

[ic98]

Hi,
Could anybody please tell me if someone can change the number of printed digits in *.ac0, or *.tr0 HSpice-output files?
For *.lis file, I can change printout accuracy using parameter NUMDGT, but this parameter doesn't work for *.ac0 files (.probe output)
When I extarct the data from a long-simulated *.ac0 file using MATLAB, since there are only 5 printed digits for every value, some of the data arrays

have the same value; although I know there is difference between these values in simulation (that is observable in *.lis file using e.g. a NUMDIG=8)
What's your suggestion? how can I apply something like NUMDIG for non-lis output files?

Thanks for your comments,
ic98

Did you try MEASDGT=x ?

Did you try MEASDGT=x ?

erild, the option you remembered is used to set the precision of values of measurements in *.ma#, *.mt#, and *.ms# files..

Can anybody suggest something else?!! thanks

... the option you remembered is used to set the precision of values of measurements in *.ma#, *.mt#, and *.ms# files..

So why not generate a *.ma#, *.mt#, or *.ms# file?

BTW: in my setup, NUMDGT=10 worked correctly for my *.ac#, or *.tr# HSpice-output files.

Hi,

If u wnt more precession with your numbers printed, then better go with default binary format for tr# , ac#( this is the case when u set post=1) then use CustomWaveview to extract the data to table format with the precession u wnt..


When ascii format is used for dumping the waveform files, the data accuracy is limited.

Thanks,

Dear Blackuni,
What is the CustomWaveview you mentioned? Is it a tool? How can I find it?
Thanks

Considering Blackuni's answer,
I wonder if can I read the binary (not-ASCII) format of HSpice-output file? what code or tool is accessible?

Thanks all

E.g. AvanWaves (from Synopsys) can display raw (=binary) output from HSpice.

Hi,

its a waveform viewer from Synopsys and provided with Hspice. or u can try Cosmosscope too.

thinking you have access to synopsys tool you can also try spice explorer it is much faster than cosmos scope
