Title: How to do line-manuplating after read in data file
Post by yaxazaa on Apr 15^th, 2006, 12:09pm

My question is how I do line by line manuplation in Verilog-A after I read in a data file contains two columns. For example: data file name is data.dat contains:
1 10
2 20
3 30

etc;

in Verilog-A:

integrer infile;
real x[0:100], y[0:100]
real z[0:100];

......

infile = $fopen("$path/data.dat");

Then What I am going to do is to assign column one as x, column two as y, and z = pow(y,x/20). HOw should I do it? Can someone help?

Thanks.

for details look at $fread $fscanf functions.. you may want to refer to Verilog-2004 manual (or Verilog-AMS 2.2 )
manual for all the details on reading files..

It looks like the data file might be formatted in a way that $table_model would work. This was added in LRM 2.2, but was already available in some simulators. Check your simulator documentation.
