Hi all,
I want to print out some data from my verilogA code. Let's say for this task I'm using code like:

Code:

$strobe("Conversion value: %6.2f (LSB)",counter_value); 

and get this response as expected: Conversion value: 700.00 (LSB)

But the question is, how can I print with parametric precision? I mean if I want change the number of digits after point according to parameter, there is a way to do it?

Following straight forward approach (create the pattern string first dependent on parameter, then strobe it) doesn't solve the problem:

Code:

parameter integer intPrecision = 2;
string strPattern;

strPattern= $sscanf("Conversion value: %%6.%df (LSB)",intPrecision);
$strobe(strPattern,counter_value); 

I get output like: Conversion value: %6.2f (LSB)  700

It means $strobe function behaves in different way for these two cases for some reason. Any suggestions about possible solution?
Thanks in advance.

Hi Geoffrey,
Thanks for your response. Unfortunately,  when trying your suggestion, I got the compilation error:

Encountered unexpected in percentage format command, '*'. Use a valid percentage format command and try again

Because for practical resasons the number of different values for precision digits is small (say 1,2,..6), I simply used the "case" statement workaround, like:

Code:

case(1)
    (intPrecision == 1) :  $strobe("Conversion value: %6.1f (LSB)",counter_value);
    (intPrecision == 2) :  $strobe("Conversion value: %6.2f (LSB)",counter_value);
    (intPrecision == 3) :  $strobe("Conversion value: %6.3f (LSB)",counter_value);
    (intPrecision == 4) :  $strobe("Conversion value: %6.4f (LSB)",counter_value);
    default                  $strobe("Conversion value: %6.1f (LSB)",counter_value);
endcase 

Of course it is so nasty (especially if you have a lot of $strobe or $fwrite statements!), but it works.
If anyone will share some magic trick to solve it in clean way, it will be good news. Meanwhile I continue with this workaround.

Thanks again for your response
