There are quite a few reasons, rather than just one single one. The
biggie IMO is that z architecture is demonically complex to implement in
silicon.
It has always amazed me that IBM is able to put out a new processor
every year or two with little or no hardware logic errors. I know from
articles in the technical journals that they do extensive testing, but
heck, in the software industry, we do extensive testing and we STILL
have to put out a significant number of fixes. Kudos to the hardware
developers!
