Are FPGA's getting too complex?

One reason we use fpgas is that they don't go obsolete in the same way as other complex chips do.

At worst the board will need minor retrack (and maybe power supply changes) for a different package, but all the logic can be carried forwards and should 'just work'.

The modern fpga are large enough to replace several big chips from only a few tears ago.

We nearly wrote a 6-port ethernet switch because the part we had been using went obsolete, but did find an alternative one.
