[sv-bc] Hierarchical seeding of random values

Section 18.14.2:

Hierarchical seeding. When a thread is created, its random state is
initialized using the next random

value from the parent thread as a seed. The three forked threads are all
seeded from the parent

thread.

Does this mean that all random states are inherited from $root?

More specifically, if I have two instances of a module with an initial block
that calls $urandom is the

value the same for both instances or are they different (example below).

Thanks,

module test;

  ranmod i0();

  ranmod i1();

endmodule

module ranmod;

integer i;

always @(i) $display("%m.i",,i);

initial

  #1 i = $urandom;

endmodule
