Hello.
How can I get frequency value or clock multiplication (division) factor from PLL block in schematic to use it in other blocks. Is it possible to send these parameters to PLL as input parameters from outside? P.S. I'm using VHDL. Thanks a lot.Link Copied

Unfortunately, the MegaWizard-generated output files are not set up to pass parameters in. You would have to hand-modify the underlying .vhd file to do this. Then you can pass the parameters in from the next highest up hierarchical module. This is relatively simple to do with source code. I'm not sure how you could do this with schematic.

You only have add the respective generics to the VHDL file, and then make Quartus generate a symbol file for it.
