How to generate Sine and triangle wave using HDL blockset?

I need to generate Sine and triangle wave using HDL blockset only. As direct waveform generator is not available in HDL blocks. Can you please suggest how to generate Sine wave and Triangle wave in which I can change Frequency and phase of waveform.

HDL blockset contains MATLAB Function block. Is it allowed?

Sawtooth matlab function is not supported by HDL coder.

You can use the NCO HDL Optimized block to generate a Sine wave.

The sawtooth can either be from a RAM (if you need it to be really simple), or with adders/subtractors and some logic for picking either increment/decrement.

You can use the HDL Counter block for this purpose or a Lookup table with the appropriate values.
