how to include a file into hspice?

Hi there,
how to include a file into hspice?
---------------------------------------------------
include file is like this
voltage time
0.000837487,0.00000000E+00
.
.
.
.
.
0.000684291,1.30208000E-08
0.000456824,2.60417000E-08
0.000175244,3.90625000E-08
and this file is a wave I want to use in input
how to write the code in hspice

Look at VPWL - piecewise linear voltage source. You might need to just add VPWL and some nodes at the start and possibly parentheses around the number list

Find here the syntax and an example:

What's this mean?
**error** the value of col1(1) or col2(2) may exceed the max column of pwl file

I suspect it doesn't like the format of your file. Try just a few lines and see if that works and gives the correct results. I suspect it may be that your input file only has CR at the end of each line instead of CR+LF but that is only a guess.

Also, it's possible that hspice doesn't like the column separation by comma (,); I've always used (and seen) white space separation.

By standard, hspice expects the order (time voltage). If you use a table the other way round, you have to tell it in the command line, something like

Vxxx n+ n- PWL PWLFILE='your_filename' col2, col1
or perhaps
Vxxx n+ n- PWL PWLFILE='your_filename' col1=2, col2=1
