HI ,

I reduced the clk frequency to 25 Mhz.But still I have the same problem.

Earlier I had negative values only in altera reserved clk (worst case slack) and altera reserved clk (Design wide TNS) .

But now at 25 Mhz I get negative values even in sopc clk.

How are these negative values goin to affect the H/W.

Can you explain?

Its my first demo with Altera and I dont understand it.
