Analyzed the PLL logic in the design and found that same clock is been connected to to two pll by using altclkctrl The out put frequency from two pll, not allowing to merge together So the input pin for the both pll is same , that makes the q...
aThere are three pieces of equipment that have been found to be vital to a drilling operation; they are they drill rig, the drilling mud, and drill bit. 有被发现重要的对钻操作的三台设备; 他们是他们凿岩机、泥浆和钻头。 [translate] atatararch tatararch [translate] ahave distinguished 3 ...
I have tried that because it seems to me that ddr3 memory controller pll can not share ref clock input as well. This causes an error message that IOPLL cascade chain of 3 or more IOPLLs was found: - the ddr3 memory controller pll - the 3rd pll - the PLL at the ...

I found this warning when I compile my project " Warning (15055): PLL "PLL:inst_PLL|altpll:altpll_component|PLL_altpll:auto_generated|pll1" input clock inclk[0] is not fully compensated and may have reduced jitter performance because it is fed by a non-...

"If you use the write_sdc command after the derive_pll_clock command, the new SDC file contains the individual create_generated_clock commands for the PLL output clock pins and not the derive_pll_clocks command." My objective here is to get the individual create_generated_clock c...
When I open up mysdc.sdc, I did not get individual create_gen_clk commands in the sdc file, instead what I get is only the command "derive_pll_clocks" in the sdc. Is my step incorrect or is the QII handbook not right (the quote above)? Can some kind souls p...
