hi, please clarify the following 

 

1. i used altpll megafunction to generate1733 Hz with 8.192 MHz as input. it accepted but while i simulating it is not giving o/p with that frequency. 

2. for all simulations it is giving 700ns delay for output 

3.how to cascade plls to get low o/p frequencies 

4. in pll what are the functions of signals pfdena,locked 

5. how the multiplication and division factors of pll mega functions are related to the M,N, COUNTER VALUE. 

6.how to get other o/ps(except dedicated o/p) of pll to externally i/o pins. 

 

with regards

hi,  

How do you have to generate, can I know the method by which you have details because I do a similar project and can be only in the steps or there are errors.
