Generating a Sine Wave

Thank you Ketan :) once again..

i am working on this just for my understanding..as i am a newbie i wanted to plot or display a sine wave from Look Up Table..

as you have said i have taken 2*pi/20 and completed 20 samples i converted them into integers upto 3 digits and took 2's compliment. these i generated in excel sheet

2*pi/20 Sin((2*Pi/3600)*S.No) I2 * 1000 INT(J2) 2's Compliment

does this work,

also the kind of DAC what we r having is 12 bit DAC , but before that i just wanted to display (probabily plot sinewave) using these values.. so can i read the above binary values using $readmemb command

and also later how can i tell simulator that i have negative numbers..please can you help me with this situation.. i think you can understand that i am a newbiein programming.

if i am wrong in any way can you suggest me more.

waiting for your reply

Thanks in advance :)
