Is clock neede in DSP builder design?

Is it necessary to add a clock in DSP builder design?

[Altera_Forum]

I'm not 100% certain on on the clock is essential, but if you don't add a clock to a DSP builder design then when you compile it you will have no clock definition (as required in the .sdc file) and it will not try to acheive a required Fmax. Also, I think it will need the clock in order to simulate the design in Simulink.

Thanx but i am talking about desinging with DSP biulder not with Simulink....

[Altera_Forum]

DSP Builder is an add-on for Simulink in MATLAB...

You need to use a clock block to derive the clock rate, else it will just assume it is running at 50 Mhz. You wont find any clock pin in the design, but after you have compile it, from the top level VHDL file, you will notice there is a clock input pin that required to connect to a clock source from hardware.

Using the DSP Builder Standard blockset you should add the Clock Block. Using DSP Builder Advanced blockset, clock settings are on the Signals block.

Yes, those blocks are needed to configure the clock setting in DSP builder design.
