but when I try to open the .tr0 file in cscope it comes out to be just blank
and also tr0 file size is 245340Bytes

Is this due to something that is/missing in accuracy options ?

Thanks

Hi,

Try to use the following in your code: .OPTION POST=1 and use .PROBE(*) for testing purpose only.
Also, try to open your .st0 file with waveviewer (wv at terminal) .

Regards.

Hi,
Thanks for reply
I tried .OPTION POST = 1 and .PROBE(*)
but its still the same

and I don't have waveviewer

I think you have to tell HSPICE the output format which your viewer (cscope ?) can understand.
