When placing an upstream IOPLL two IO sub-banks away from the downstream IOPLL when using IOPLL cascading with Agilex™ 7 F-series and I-series, the Quartus® Prime Pro Edition Software will issue the following error:
Error(14566): The Fitter cannot place 1 periphery component(s) due to conflicts with existing constraints (1 IOPLL(s)).
Fix the errors described in the sub-messages, and then rerun the Fitter.
The FPGA Knowledge Database may also contain articles on resolving this periphery placement failure. Review the errors and then visit the Knowledge Database at https://www.intel.com/content/www/us/en/support/programmable/kdb-filter.html and search for this specific error message number.
