HwAcc/F/09-Ethernet-Alveo x4 on U200

Hi

I was trying to go thru the 09-Ethernet-Alveo using LANE=4

However, vitis was not able to complete the implementation and leaving an error of below

[Constraints 18-1000] Routing results verification failed due to partially-conflicted nets (Up to first 10 of violated nets): level0_i/ulp/eth0/inst/i_ethernet_0/inst/i_core_gtwiz_userclk_tx_inst_1/gen_gtwiz_userclk_tx_main.bufg_gt_usrclk_inst_0 level0_i/ulp/memory_subsystem/inst/memory/ddr4_mem02/inst/u_ddr4_mem_intfc/u_mig_ddr4_phy/inst/u_ddr4_phy_pll/xlnx_opt_

Would like to know how to solve the above errors?

Thanks

Hi @Rampagee , could you help with this issue?

[Rampagee]

Hi, @eerobert, are you using all the default configuration with "make all LANE=4" command to build? Could you provide the platform and Vitis version, as well as the GitHub repo branch you are using (such as 2022.2, 2022.1, etc.)? Thanks.

i edit the makefile and change LANE := 1 to LANE := 4 and i am checking out 2022.1 branch and compiled with vivado 2022.1

Hi, @eerobert, I tried and re-product the issue, I will dig into this and please use 2022.2 version temporarily. Thanks.
