manual clock

Hi there,

I am fresh new to Quartus/Cyclone and Everything related to them.

My first project at school consits of downloading a circuit to Cyclone II board and demonstrating that its output is correct.

What I am having problem at is the clock . I want the clock to be an input pin, by which I mean , I want to send out a clock signal every time I want (by turning on & off a switch or by using a push button on the board) and not have any internal or automatic clock.

I was trying to do something on my own with Timing Analysis Settings, but I think i messed up things even worse.

Right now I get the following warnings when compiling the project:

warning: Can't achieve timing requirement Minimum Pulse Width Requirement (Low) along 3 path(s). See Report window for details.

critical warning: Timing requirements for slow timing model timing analysis were not met. See Report window for details.

warning: Found 3 output pins without output pin load capacitance assignment

Info: Pin "A" has no specified output pin load capacitance -- assuming default load capacitance of 0 pF for timing analysis

Info: Pin "B" has no specified output pin load capacitance -- assuming default load capacitance of 0 pF for timing analysis

Info: Pin "C" has no specified output pin load capacitance -- assuming default load capacitance of 0 pF for timing analysis

warning: The Reserve All Unused Pins setting has not been specified, and will default to 'As output driving ground'.

Below is also a part of the circuit if helpful.

How can I set this up ?

Thank you
