well all those errors have disappeared happily, without schmit trigger
or any other magic

Just what was the change anyway? Getting rid of using the strobe to clock
things or something else?

KJ

well as soon as the strobe is passing one FF clocked at 50mhz
there was measurable error rate for both extra and missing strobes.

thats basically it. I had some of the design tested on Xilinx and bad-
proto
where I had to filter the signals, so at design change i removed some
filters
and in the strobe left 1 FF what looked like good solution until i did
start
to measure the actual error rate..
