In some cases, attempting to link Exostiv Core Inserter for AMD software to Vivado hangs or does not work.

There are 2 ways of linking the core inserter to Vivado in netist mode:

1) Open your synthesized project in Vivado and launch Exostiv Core Inserter separately. Then click the Exostiv button in Vivado: a window opens where you select the Core Inserter instance to link to.

2) Open your synthesized project in Vivado and then hit right away on the Vivado button. In this case, the core inserter should open automatically and be linked to Vivado without seeing the selection window.

This issue likely originates from a firewall setting: we use a local network connection to link our software to Vivado. It does not require an actual network but could be blocked by firewall programs.

Please make sure to properly set up your firewall program and accept the connection started then so it can go through.

Technically, the Vivado shortcut will lead to opening a port through which the core inserter and Vivado will communicate.
So, the firewall application should not block this simple TCP protocol communication: both Vivado and Exostiv_CI_A processes must go through.

The following Linux command allows filtering the opened port: “sudo netstat -ntlp | grep -i vivado”
