Hi all,

In LRM version 1.4 there was an explicit restriction in terms of implicit nets and its usage in behavioural context.

module blackbox;

child chd1 (a); // implicit net "a" allowed in structural syntax
analog begin
  V(b) <+ 10; // implicit net "b" disallowed in behavioural syntax
end

endmodule

The above usage, where net "b" not having a declaration was explicitly disallowed in the LRM when used within analog begin-end. However, this restriction seems to have been removed from LRM2.0.

So i just wanted to know the current status of this, and is it allowed to have implicit nets in the behaviour.

Regards,
Sri
