Why does an IOPLL Intel® FPGA IP with dynamic reconfiguration enabled not lock during simulation when the mgmt_clk port is connected to an output clock of another IOPLL Intel® FPGA IP when using Intel® Cyclone® 10 devices? - Why does an IOPLL Intel® FPGA IP with dynamic reconfiguration enabled not lock during simulation when the mgmt_clk port is connected to an output clock of another IOPLL Intel® FPGA IP when using Intel® Cyclone® 10 devices? Description During simulation, an IOPLL Intel® FPGA IP with dynamic reconfiguration enabled may fail to lock when the mgmt_clk port of the PLL Reconfig Intel® FPGA IP is connected to an output clock of another IOPLL Intel® FPGA IP in Intel® Cyclone® 10 devices. This behavior is only seen during simulation and doesn't appear in hardware. Resolution As a workaround, connect the mgmt_clk port on the PLL Reconfig Intel® FPGA IP to a free running clock.
