Introduction – Addressing Core Industry Needs and Solutions
Hardware verification engineers, software analysts, and AI planning specialists face a critical computational challenge: complex systems (chip designs, software code, schedules, security protocols) involve thousands to millions of variables and constraints (Boolean logic, linear/nonlinear equations, temporal relationships). Manual analysis is impossible; brute-force search is exponentially slow. A logical constraint solver is an intelligent computing tool based on logical reasoning and constraint satisfaction techniques, capable of automatically solving problems involving variables, constraints, and logical relationships. It typically combines formal descriptions such as first-order logic, Boolean logic, linear/nonlinear constraints, and temporal logic. Through search, propagation, pruning, and optimization algorithms, it quickly determines whether a set of constraints is satisfiable and either provides a solution that satisfies the conditions or proves that it is unsatisfiable. This type of solver is widely used in formal verification, program analysis, artificial intelligence planning, optimal scheduling, and security protocol verification, serving as a crucial foundational tool for intelligent decision-making and automated reasoning. Key technologies include SAT (Boolean satisfiability), SMT (satisfiability modulo theories), ILP (integer linear programming), and CP (constraint programming).

3. Industry Vertical Differentiation: SAT vs. SMT vs. ILP vs. CP
| Parameter | SAT (Boolean) | SMT (Modulo Theories) | ILP/MILP | CP (Constraint Programming) |
|---|---|---|---|---|
| Variable types | Boolean (true/false) | Boolean + bit-vectors, integers, reals, arrays, etc. | Integer, real (linear objective + constraints) | Integer, real, set, sequence (nonlinear) |
| Constraint types | CNF clauses | First-order logic + theory-specific | Linear equalities/inequalities | Arbitrary (global constraints, alldifferent, etc.) |
| Typical problem size | 10M+ variables | 100K-1M variables | 10K-100K variables | 10K-100K variables |
| Optimization | No (satisfiability only) | No (satisfiability only) | Yes (objective function) | Yes (branch-and-bound) |
| Key algorithms | CDCL (conflict-driven clause learning) | CDCL + theory solvers | Branch-and-cut, simplex | Backtracking, propagation, heuristic search |
| EDA applications | Equivalence checking, ATPG | Property checking, model checking, symbolic execution | Floorplanning, routing | Scheduling, resource allocation |
