Sine and Cosine HDL Optimised Block

Is there an example of how to use the Sine and Cose HDL Optimised block to generate sine wave. I want to generate HDL using this block.

Thank you!

Please find attached a basic model using the block.

The Sine HDL Optimized block and Cosine HDL Optimized block implements a fixed-point sine or cosine wave by using a lookup table method that exploits quarter-wave symmetry.

Depending on your selection of the Output formula parameter, the blocks can output these functions of the input signal:

• sin(2πu)
• cos(2πu)
• exp(i2πu)
• sin(2πu) and cos(2πu)
