How can I use clock signal

Thanks for the reply but the problem remains;

All the registered DSP builder blocks uses an internal clock. I can just instantialte the clock block, I cannot connect it to any other blcok.

On the basis of the registered dsp blocks (which uses the internal clock) I have developed my logic. Now I want to connect the same clock to a non registered blcok.

Kindly let me know if any body know it.

Hi!

I also had a problem with the usage of the clock signal in DSP Builder.

I tried to implement a clock recovery for a transceiver and I finally gave it up.

I know how to set a clock, how to derive it or how to use a pll, but I think it is not possible with the DSP Builder to have the clock as "signal line"

So if you have any clues I would be glad to hear them.

I now implement basic logic in quartus II and import more complex funktions then from generated vhd files from DSP Builder.
