PROTOTYPES, INTEGRATED circuits, WELDING, ELECTRONIC apparatus & appliances, RADIO frequency, and ELECTRICAL engineering
The article focuses on prototyping techniques. According to the article, this has become more difficult as the years pass. Tiny components and high-frequency circuits now demand rigorous prototyping methods. Prototyping requires a full complement of magnifiers, microscopes, lamps and tweezers. It also notes that one of the fastest ways to prototype a circuit is the dead bug technique. It uses a solid, copper-clad board as a ground plane. Meanwhile, a wire-tapped prototype is suitable for low-frequency designs. Another method is to use perforated board with solder pads or with both solder pads and plated-through holes.
This article describes the key process requirements for integrated circuit (IC) prototyping as well as its objectives and benefits for netlist and constraint handling, placement, power and signal routing, and analysis. The primary categories of chip-design specifications are based on functionality, timing, power and area. For a successful IC prototyping strategy, designers are required to start working early with design data, which may be incomplete or inaccurate. When placing IC prototypes, the objectives should center on the principal floor plan elements.
PROTOTYPES, INTEGRATED circuits, APPLICATION-specific integrated circuits, SYSTEMS on a chip, and EMBEDDED computer systems
This article focuses on prototyping application specific integrated circuits (ASIC) and systems on chips (SOC). Prototyping ASIC and SOC is essentially a step backward--turning an SOC into what some refer to half-jokingly as a system on board. In building a prototyping system, some designers reconstruct the functions of their ASIC using a mixture of discrete components, legacy ASIC, and FPGA providing new functions. The drawback of ASIC prototypes, however, is that they are harder to debug because it is difficult for designers to pinpoint the exact location of a bug on these systems. On the other hand, building a prototyping system from scratch is in some ways easier and in other ways harder to do than it was in the past.
PROTOTYPES, RAPID prototyping, COST effectiveness, INDUSTRIAL applications, PROGRAMMING of numerically controlled machine tools, and MOLDING (Founding)
The article discusses the additive and accelerated conventional methods in prototype designing. It mentions that the addition of the additive processes has allowed prototyping to take a step forward in time and cost savings. It states that the rapid injection molding and automated computer numerical control (CNC) machining methods have closed the gap of speed and cost saving.

The article looks at how designers can maximize the benefits of converting field programmable gate arrays (FPGAs) to application specific integrated circuits (ASICs). It stresses the importance of designing the power-supply scheme for the FPGA core supplies in such a way that they can later be easily changed to another voltage. Boundary-scan-test dependencies can also yield cost savings. It also mentions the importance of timing budgets for the device operating in the system. It offers guidelines on configuration and start-up.
INDUSTRIAL research, RAPID prototyping, PROTOTYPES, and ELECTRONIC systems
The article presents the findings of a study on the accuracy of three-dimensional printing and desktop modeling systems conducted by engineer Todd Grimm. The study investigated the dimensional accuracy of Z Corp.'s ZPrinter 310, 3D Systems Corp.s' InVisionSR, and Stratasys Inc.'s Dimension SST. The study showed that the Dimension machine was the best performing prototype among the three systems tested. The study also proved that the resolution does not directly equate to dimensional accuracy.
