Virtual interface connection in class

UVM
1

Can we connect two virtual interfaces at runtime in any of the tasks in the uvm testbench? Not just driving a value but concurrent coonnection. something like:

…
vif1.data_in=vif2.data_out;
vif2.data_in=vif1.data_out
…

In reply to manjubshetty:

You’ll have to do this in a fork’ed process

fork 
   forever @(vif2.data_out) vif1.data_in=vif2.data_out;
   forever @(vif1.data_out) vif2.data_in=vif1.data_out;
join_none

This might be painfully slow if you have many signals like this.
