Routing errors after adding ILA to design

Hello,

in my design I'm using the AXI Ethernet Lite IP Core which is connected to SJA1105 Ethernet switch (behaves like a PHY). After booting Linux I can see the Emaclite interface and receive data from a node, which is also connected to the switch. Unfortunatelly, I can't ping this node from my Emaclite and this node does'nt receive any data from Emaclite as well. So I added an ILA core to check the receiving and transmitting signals. 
After adding the ILA to my design I have now a routing error in the implementation phase (please see the attachments). 
Can someone please help me to solve his issue?

Best regards,
Usam

Re: Routing errors after adding ILA to design

Hi @usam95 ,

Open the implemented design and check the net connections of unrouted net,  Use the below AR as an initial reference point:

Re: Routing errors after adding ILA to design

Hi @usam95 

Also re-routing a failing net after the failure should give more helpful information. Normally, this would show the source and destination site pins, which can help to understand if this is an unroutable connection, or possibly congestion related.
