We had a problem with Spartan-6 Icap. We use a ICAP instance in our design to reset the board after update the Flash.
When we change "map options" or change a little in design, sometimes ICAP does not work correctly. We think that ICAP need some timing constraints, But we do not know them.
What can we do for ICAP stability? we want that it works anytime after synthesize.
Does our design need timing constraints?
