Hi,

I see the following on the language reference document. After I look around for some time, I still do not understand what "A a1()" means.

Could you help me on this question?


Thanks,




module top;
A a1();
B b1();
endmodule
module A;
electrical n,p;
branch (n,p) b;
analog V(b) <+ 1.34;
endmodule
module B;
analog $strobe("voltage == %g", V(top.a1.b));
endmodule
