hi,

these are the timing related warnings i am getting

warning:

1.at least one of the filters had some problems and could not be matched.

2.the following clock transfers have no clock uncertainity assignment

3.critical warning: timing requirements not met.

4.critical warning: found minimum pulse width or period violations. see report minimum width for details.

i dont know how to overcome these.

sorry my questions may seem silly, but i cant help this is my first experiance with altera environment.

am using cyclone iii dev board ( ep3c25f324c6).

my mentor said it is some interrupt related error. is that the one causing problem...?

thank you.
