Since my 'sig3' vector is four bits wide, the signal from the CE logic
needs to
fan out to the 4 flip flops. Now we get routing delay.

Antti's example may be correct, but for the 4 bit wide destination, I
think
I get a performance penalty.

I love synthesis, but... It sure would be nice to have any easier way
to
direct it! In any event, it sure beats schematics.
