Si list,

My company once had a design working for several years until they shrank
the die of a CPLD. Since then we had been experiencing sporadic failures
and crashes until we found a solution. ( Terminating a few critical
input signals ). So far not much new.
My question is does any body know what could be the effects of a die
shrink ( besides time delay and rise/fall time) on a component like a
CPLD 2000 gates. I compared timing delays and rise time between the two
processes and there were ( as claimed by the manufacturer ) almost the
same.
I could never get any clear answer from the manufacturer.

Thanks
