How to eliminate sporadic errors on Stratix-V designs?

Jan,

Thank you for the reply. As you say large designs do require more power and we are checking into that as a possible cause. It is in our pipeline to get a power source that supports higher current to see whether it makes a difference. As it is we don't see dips in the core voltage when we put a scope on it. And the temperature of the part does not measure as excessive. We do have heat sinks.

Regards,

John
