Once upon a time all IC design was done directly on film on a large light table, so what?
Transistor count is a more useful metric with FPGAs currently hitting 30 billion. NAND Flash has even higher densities than that. But considering the op is here asking about VLSI tools I hardly think he needs the complexity of "big data" tools.
Seriously? This is the biggest shortcoming? Wishbone bus?
Do you know of a Fab that accepts Gerber files? While the industry standard is OASIS I believe GDSII is still common.
Unfortunately that is what some believe, but it couldn't be further from the truth.
The short answer to the op's question would be no. The longer answer would be definitely not.
