(PR-Impl error): [Route 35-451] Routing/Distribution Layer congestion detected on net AND [Constraints 18-1000] error.

Hello,

Vivado 2019.1 Ultrascale+ Partial reconfiguration flow

During implementation I get Critical Warnings that lead to an error.

 

[Route 35-451] Routing/Distribution Layer congestion detected on net qsfp1_instance/inst/i_core_gtwiz_userclk_tx_inst_0/CLK
[Constraints 18-1000] Routing results verification failed due to partially-conflicted nets (Up to first 10 of violated nets):  qsfp1_instance/inst/i_core_gtwiz_userclk_rx_inst_0/CLK qsfp1_instance/inst/i_core_gtwiz_userclk_tx_inst_0/CLK prsfp2_instance/qsfp2_instance/inst/i_core_gtwiz_userclk_rx_inst_0/CLK prsfp2_instance/qsfp2_instance/inst/i_core_gtwiz_userclk_tx_inst_0/CLK 

How can I debug that? I don't find any trace of Route 35-451 and Constraints 18-1000.

Thank you.

Hi, @alexis_jp ,

Please confirm that the mentioned clock nets can be routed correctly in the non-PR flow first.
