Honored ContributorHello, I want to implement sine and cosine signals in vhdl to check a part of my code but i don't know how to initialize these sin and cos signals? please tell me what is the way to do it?
i have read that it is possible through LUT but i don't know what LUT is ???
Honored ContributorThe wave screenshot posted above already shows a different problem than what you have reported initially. The negative values are not replaced with zeros anymore, rather you seem to be missing the sign bit this time. You need to inspect the values shown in the diagram to be able to tell what's happening - for example, what is the value at the peak of the sinusoid? For 16bit signed integer, your values in the LUT/MIF should be in the [-32768;+32767] interval, are they?
