Perl code for checking for number good die in wafermap

[eadavid]

HI,
I am a beginner to perl and I need to write perl code for checking a good die in the wafermap.

Here is the wafermap look like in file

....XXXX111111111X1111XXXX....
..1X1111111X111111111X111X..

I need help in perl code to check number of 1 (good die) and to check X for (bad die). After it read the file it should print out total number of 1 and X.

Anything it help.

Thank you in advance for your help and time.

Hi David!

Try this:

@wafermaps = (
  "XXXX111111111X1111XXXX",
  "1X1111111X111111111X111X",
);
 
for $wafermap ( @wafermaps ) {
  $one = () = $wafermap =~ m/1/g;
  $ex  = () = $wafermap =~ m/X/g;
 
  printf("----------- $wafermap ----------\n");
  printf("one's: $one\n");
  printf("ex's : $ex\n");
}
