Refer to the highlighted column in Figure 2–9 of the clock transfer report
and PLL_Names.txt for the following procedures:
1. From the clock transfer report, trace the pin or port under "From
Clock".
For example, altpll0:PLL0|altpll"altpll_component|_clk1.
2. Refer to the PLL_Name.txt file to and see what the PLL index is
associated to.
For example, altpll0:PLL0|altpll"altpll_component associates to
PLL_2.
3. From the clock transfer report, trace the pin or port under "To
Clock".
For example, altpll0:PLL1|altpll"altpll_component|_clk0.
4. Refer to the PLL_Name.txt file in Figure 2–9 to see what the PLL
index associated to.
For example, altpll0:PLL1|altpll"altpll_component associates to
PLL_1.
You now know the source clock from PLL_2 and the destination
clock from PLL_1.
5. Enter 2 and 1 into the first PLL cell of the source clock and the
destination clock, respectively, as shown in Figure 2–10 on
page 2–10 .
