Honored ContributorHow to create sine and cos waves of different frequencies using Cyclone III(VHDL)
Hi, Is there anyone can help me to deal with one problem: How to create sine or cos waves in Cyclone III FPGA in VHDL. I have no clear idea to program the VHDL code although I have search some ...

Honored ContributorIf you have no VHDL knowledge, my first suggestion would be to find a good tutorial and get yourself familiar with the language.
As for the sin waves, sine and cosine are identical, but with a phase shift. It would be easy enough to build a ROM of sin values in VHDL and just read them out.
