Given huge design time and 12 week turn around from tape-out to first
silicon they wanted to make sure the design was correct - errors
could set the product availablity by 6 months or more. This was
before the availability of sophisticated simulations and copious
cheap CPU cycles. And, it was far more complex than any chip ever
buil before. As it turned out, it was a big waste of money.
