  2. Design closure - Wikipedia

    en.wikipedia.org/wiki/Design_closure

    The complexity of the flow is a direct result of the addition and evolution of the list of design closure constraints. To understand this evolution it is important to understand the life cycle of a design constraint. In general, design constraints influence the design flow via the following five-stage evolution:

  3. Constraint (computer-aided design) - Wikipedia

    en.wikipedia.org/wiki/Constraint_(computer-aided...

    The shaft and pulleys share a common centerline. The constraints of the key are set in relation to the keyseat. A constraint in computer-aided design (CAD) software is a limitation or restriction imposed by a designer or an engineer upon geometric properties [1]: 203 of an entity of a design model (i.e. sketch) that maintains its structure as the model is manipulated.

  4. Design optimization - Wikipedia

    en.wikipedia.org/wiki/Design_optimization

    Design optimization applies the methods of mathematical optimization to design problem formulations and it is sometimes used interchangeably with the term engineering optimization. When the objective function f is a vector rather than a scalar , the problem becomes a multi-objective optimization one.

  5. Design rule checking - Wikipedia

    en.wikipedia.org/wiki/Design_rule_checking

    In electronic design automation, a design rule is a geometric constraint imposed on circuit board, semiconductor device, and integrated circuit (IC) designers to ensure their designs function properly, reliably, and can be produced with acceptable yield. Design rules for production are developed by process engineers based on the capability of ...

  6. Hardware architecture - Wikipedia

    en.wikipedia.org/wiki/Hardware_architecture

    It is a process because a sequence of steps is prescribed to produce or change the architecture, and/or a design from that architecture, of a hardware system within a set of constraints. It is a discipline because a body of knowledge is used to inform practitioners as to the most effective way to design the system within a set of constraints.

  7. Topology optimization - Wikipedia

    en.wikipedia.org/wiki/Topology_optimization

    Topology optimization is a mathematical method that optimizes material layout within a given design space, for a given set of loads, boundary conditions and constraints with the goal of maximizing the performance of the system.

  8. Theory of constraints - Wikipedia

    en.wikipedia.org/wiki/Theory_of_constraints

    The theory of constraints (TOC) is a management paradigm that views any manageable system as being limited in achieving more of its goals by a very small number of constraints. There is always at least one constraint, and TOC uses a focusing process to identify the constraint and restructure the rest of the organization around it.

  9. Engineering design process - Wikipedia

    en.wikipedia.org/wiki/Engineering_design_process

    The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
