Quartus prime pro 20.1
Use the LVDS SERDES inter FPGA IP
The IP core is configured as follows
General Settings
FUNCTIONAL MODE:TX
Number of channels:5
Data rate:616.0 Mbps
SERDES factor:7
PLL Settings
Desired inclock frequency:88.0MHz
Enable pll_areset port(selected)
Transmitter Settings
Tx core registers clock:tx_coreclock
wire [4:0] tx_out_y;
assign cl_y_p = tx_out_y[3:0] ;
assign cl_yclk_p = tx_out_y[4] ;
output [3:0] cl_y_p,
output cl_yclk_p,

When compiling, it prompts an error, the error is as follows
The permit_cal input port of IOPLL "Cam_full_altera|cam_y_serdes|lvds_0|core|arch_inst|pll_inst|internal_pll|stratix10_altera_iopll_i|s10_iopll.fourteennm_pll" is not connected correctly. Enable and export the permit_cal port of downstream IOPLL "Cam_full_altera|cam_y_serdes|lvds_0|core|arch_inst|pll_inst|internal_pll|stratix10_altera_iopll_i|s10_iopll.fourteennm_pll" with the Platform Designer GUI and connect to the locked output of upstream IOPLL "sys_pll_inst|iopll_0|stratix10_altera_iopll_i|s10_iopll.fourteennm_pll"
