About maximum RAM data rate in Stratix II

--- Quote Start ---

Whatever you build, the best one to tell you is the tool itself.

You set your clock speeds in sdc and see what fmax is achieved whether in the logic fabric or the ram blocks...

I set the clock speeds at 250MHz and the achieved fmax is about 300MHz in the Classic Timing Analysis report.

Could you please tell me where to find the fmax of the logic fabric or the ram blocks in detail? And what is sdc?

Thanks.
