Why do I see warning messages during Serial Lite IV FPGA IP design compilation using the Quartus® Prime Pro Edition Software version 23.1?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 23.1, you might see the following  or similar warning messages while compiling the Serial Lite IV FPGA IP designs targeting Stratix® 10 and Agilex™ 7 devices:

• Warning(14284): Synthesized away the following node(s)
• Warning(14285): Synthesized away the following node(s) of type RAM
• Warning(14320): Synthesized away node "*|inst_sl4_phy|inst_ehip_xcvr*|tx_ready_sync_fifo|dcfifo_component|auto_generated|fifo_lutram|dataout_wire[0]" 
• Warning(14320): Synthesized away node "*|inst_sl4_phy|inst_ehip_xcvr*|DESKEW.PCSDIRECT.rx_pcs64_dsk_inst|lane_loop[*].lane_delay|sm0|rdata[*]" 

It is safe to ignore these messages.

Resolution

No workaround is required. It is not impacting functionality. 

This problem is fixed in the Quartus® Prime Pro Edition Software version 23.3.
