error : selected device has 126 RAM location(s) of type M9k.

I made the signal with NCO IP. We then testbench the signal. First, I added .sip and .qip files to the project and compiled the following code. But I got an error and I do not know why.

The device you're targeting doesn't have enough memory resources to implement the IP you're instantiating. Try compiling it for a larger device.

If that is your chip, then the IP you have created will not fit into it, and you will either need to modify the IP or buy a new device.

You certainly can. I believe you have entered excessive figures for lut size (phase resolution). try 2^10 fr phase, 2^10 for amplitude.
