When you compile the Intel® Stratix® 10 Hard IP for PCI* Express MX H-Tile ES1 FPGA Devkit Design Example with any feature enabled in the Configuration, Debug and Extension Options tab via the Intel Stratix 10 PCIe* IP Parameter Editor, you may see the following Fitter error messages:
Error(175020): The Fitter cannot place logic pin that is part of pcie_example_design pcie_example_design in region (95, 2) to (95, 2), to which it is constrained, because there are no valid locations in the region for logic of this type.
Error(16234): No legal location could be found out of 1 considered location(s).
Error(175005): Could not find a location with: IO_FUNCTION of GPIO (1 location affected) .
Error(14566): The Fitter cannot place 1 periphery component(s) due to conflicts with existing constraints (1 pin(s)).
Error(15307): Cannot apply project assignments to the design due to illegal or conflicting assignments.
The Fitter error messages are due to the invalid reconfiguration clock pin location assignments in the Intel Stratix 10 Hard IP for PCI Express MX H-Tile ES1 FPGA Devkit Design Example.
