How to generate values for my sine lut

I want to generate a sine wave with lut approach in verilog using Spartan6 FPGA. How do I generate those values? what should be the difference between the angles and how to determine the number of table entries ? Thanks in advance.

    I'd use Microsoft Excel or similar to generate your sin values. The more entries in the table (and the wider the entries) the more accurate your sin wave will be.

    PS. A word of warning - I suspect Sp****n6 is a bit of a swear word on an Altera forum...:oops:
