Metastability is an unstable state, and getting a register to be metastable is akin to balancing a marble on the peak of a sombrero. ;) So basically, if the first register manages to become metastable, the probability that the second will become metastable is very low -- so the probability of the pair becoming metastable is close to infinitesmal. I've used this technique in asynchronous buses before, and it seems to work really well... *shrug* HTH, Peter _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
