Hi guys,
I am trying to add a remote update functionality to my design.
It is Cyclone EP3C25E144C8 with Nios system on it.
When I add a Remote Update Controller to the SOPC system and recompile my project, Timing analysis fails. This critical path is inside the remote controller and relates to its clock.
At first, I fed a 40 MHz clock to the controller, as recommended in datasheet.
When timing failed, I lowered frequency down to 25 MHz. But timing analysis fails again, and the slack (negative) is worse than that at 40MHz!
Then down to 10 MHz - and again no success.
The problem is in clock hold, so I think lowering clock frequency
won't help. It's rather the design of the remote update component...
Have you got this problem?I need your advise.Thanks a lot!
