Critical Issue
If you attempt to instantiate two CPRI channels with PLL phase circuitry detector (PFD) feedback turned on, the Fitter generates errors similar to the following:
Error: Following nodes use the same resource INTERQUAD_TXRX_CLK_X0_Y28_N0_I3
Error: Node "lib_xcvr_channel_module:channel_inst0|rx_pcs_clkout"
is currently placed at location RXPCS_X0_Y16_N8 with a Global Signal
type of Auto
Error: Node "lib_xcvr_channel_module:channel_inst1|rx_pcs_clkout"
is currently placed at location RXPCS_X0_Y22_N8 with a Global Signal
type of Auto
These errors occur because the Fitter is unable to place the two CPRI channel automatically.
Use the quartus_cbf.exe command line executable to regenerate the .hexout file, or close and then reopen the Convert Programming Files dialog box before regenerating the file.
