Variant sink blocks are mainly used to activate at most one output port during the simulation. Based on the variant condition specified only one block gets activated and the block attached to inactive port will be removed from the simulation.

For example, if the variant for output port 1 is v==1 and for output port 2 is v==2. Then based on the value of 'v' only one of the output block gets activated and other gets removed during simulation.
