1. A system for designing a circuitry configuration of heat-exchanger units, comprising:
an interface to acquire design parameters of the heat-exchanger units, wherein the design parameters include a number of tubes and a number of pre-existing connections, minimum and maximum number of circuits, a maximum length of the circuits, a maximum distance between connections of the tubes;
a memory to store the design parameters, a set of configurations of heat-exchanger units and computer-executable programs including a relaxed decision diagram formation module;
a processor, in connection with the memory, configured to perform steps according to the computer-executable programs, wherein the steps comprising:
generating a relaxed decision diagram for each of the heat-exchanger units based on the design parameters of the heat-exchanger units by executing the relaxed decision diagram formation module, wherein the relaxed decision diagram defines pre-connected tubes as super-nodes treated as one heat-exchanger unit;
creating constraints with respect to connections of the heat-exchanger units according to the relaxed decision diagram, wherein the constraints include location of inlet tubes and location of outlet tubes; and
generating feasible configurations of the heat-exchanger units by using the constraints.
