Meanning of ideal nets

[evesjh77]

In IC Compiler, there is a command all_ideal_nets.
But I don't know what it is....
I think it is net that is not routed.
But that command is executed pre Route stage.
Please tell me about that..

Ideal net means no RC could be associated to this net and the timing is independently of the routing.
It is only before routing you could used that, for example if you want to apply a specific buffer tree for huge fanout nets like scan enable, reset.
