Cyclone III - Remote Update - Clock Hold Time Violation

Hi,

I am using the altremote_update in Cyclone III. While the basic functionality works fine, it looks like the reading of the param-registers, esp. the reconfiguration trigger conditions, is incorrect. In the timing analyzer I see a hold-time-violation inside the alteremote_update-block. It is about 1ns from ...|dffe22 to ...|wire_sd4_regout. Maybe this is the cause of the problem.

Does anybody else see this, or is this specific to my design in any way? Does anybody know how to solve this? Or can it be safely ignored?

Regards,

Thomas

    Hi,

    Did you ever solve this problem? I'm getting similar timing warnings.
