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 Update any outdated transceiver PHY IP cores, correct any illegal pin assignments, and then recompile your design.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

Due to a problem in the Intel® Quartus® Prime Pro Edition software version 18.0, fitter errors may occur with example design of the Intel® Stratix® 10 Low Latency 40G Ethernet Intel FPGA IP when VCCR_GXB and VCCT_GXB supply voltage is set to 1_1V, because generated PLL's voltage mismatch.

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 Update any outdated transceiver PHY IP cores, correct any illegal pin assignments, and then recompile your design.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(15744): In atom 'av_top|alt_e40_0|tx_pll_gen.tx_pll|s10_fpll_tx|fpll_inst'

Error(15744): The settings must match one or more of these conditions: 

Error(15744): ( VCCR_GXB/VCCT_GXB == 1_1V ) 

Error(15744): But the following assignments violate the above conditions: 

Error(15744): VCCR_GXB/VCCT_GXB == 1_0V

Error(15744): Or the settings must match one or more of these conditions: 

Error(15744): ( VCCR_GXB/VCCT_GXB == 0_9V ) 

Error(15744): And the following assignments violate the above conditions: 

Error(15744): VCCR_GXB/VCCT_GXB == 1_0V

Error(15744): In atom 'av_top|alt_e40_0|pma_40g|s10_native_phy|s10_xcvr_10g_4channel|g_xcvr_native_insts[0].ct2_xcvr_native_inst|inst_ct2_xcvr_channel_multi|gen_rev.ct2_xcvr_channel_inst|gen_ct1_hssi_cr2_pma_tx_buf.inst_ct1_hssi_cr2_pma_tx_buf'

Error(15744): The settings must match one or more of these conditions:  Error(15744): ( VCCR_GXB/VCCT_GXB == 1_0V ) 

Error(15744): But the following assignments violate the above conditions:  Error(15744): VCCR_GXB/VCCT_GXB == 1_1V

Error(12274): A critical error occurred while the periphery placement was committed to the atom netlist. The atom netlist is now invalid and the Fitter must be restarted.  

Workaround/Fix

This problem has been fixed in the Intel® Quartus® Prime Pro Edition software version 18.0.1 and 18.1.
