is it mandatory to have FDB software for design to submit to a company or could one use the old pad and paper, and or a MS word to do the job?

Thank You,

It's best to have it as neat as possible.

If nothing else, you could even use MS Paint to draw boxes and fill in the text.

If you didn't have an office package, you could download OpenOffice or StarOffice and use one or more of those tools.
