Error (15653): The Fitter cannot find a legal configuration for the following atoms. Update any outdated transceiver PHY IP cores, correct any illegal pin assignments, and then recompile your design. - Error (15653): The Fitter cannot find a legal configuration for the following atoms. Update any outdated transceiver PHY IP cores, correct any illegal pin assignments, and then recompile your design. Description You may see this error message in the Intel® Quartus® Prime Fitter when you instantiate the "tx_pma_div_clkout" port of a Native Phy IP with data rates below 5 Gbps in Arria® 10 devices in Quartus® Prime Software16.1 and 17.0. Due to a problem with the Native Phy IP, the following error messages are missing. Error (15744): The settings must match one or more of these conditions: Error (15744): ( datarate_bps > 4999999999 ) OR ( rser_clk_divtx_user_sel == DIVTX_USER_OFF ) Error (15744): But the following assignments violate the above conditions: Resolution To work around this problem, you can increase your data rate or disable the "tx_pma_div_clkout" port.
