You could enter all the data (component types and counts) into a file
and then use R to multiply and add.  R is a little more than you need to
perform a parts count 217 analysis or a part stress analysis for that
matter.  A spreadsheet would suffice for something as small as 700
components if you don't want to or can't use something like Relex,
Reliasoft, Item, etc.
