AddTest ​

Adds two constant values to produce a sum of 3.

This component demonstrates basic component composition by connecting two constant sources (with values 1 and 2) to an adder block. The output of the adder (add.y) equals the sum of the two inputs (3).

Usage ​

AddTest()

Behavior ​

add.u1(t)=c1.y(t)add.u2(t)=c2.y(t)c1.y(t)=c1.kc2.y(t)=c2.kadd.y(t)=add.k1add.u1(t)+add.k2add.u2(t)
