cyclone3 pll

dear fvm please clarify some doubts regarding cyclone3 pll,

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
