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.

The article describes a testbench which is constructed using the microcontroller in a project to simplify the new-task learning curve. Almost every engineer can take advantage of the widespread availability of evaluation boards and modules for low- to high-end devices. Among the advantages of early testbench development is accelerating the time it takes to integrate the firmware once real hardware is available. The major characteristics that make an evaluation board a good testbench include a generous prototyping area.
This article reports on the National Instruments (NI) Week that took place in Austin, Texas, on August 17 through 19, 2004. For years, National Instruments has been hugely successful at applying its concept of virtual instrumentation, especially in automated testing and test-oriented laboratories. The LabView environment, however, hasn't been ideal for design engineers who need to make signal measurements in the design and prototyping stage of a project. At NI Week, however, the company announced its intention to offer products for the design process--first, for prototyping and later in the form of development tools. NI Week included a roster of new modular instruments that engineers can meld into customized test systems. Perhaps the biggest such announcement this year was the new M Series DAQ (data-acquisition) modules, including analog- I/O, digital-I/0, and counter/ timer products. Input sampling rates range from 250k to 1.25M samples/sec, and the units offer 16- to 18-bit precision. Prices start at $375. But, this year at NI Week, the emphasis on designers stole the show. NI revealed the SignalExpress software platform, which can leverage the same virtual instruments that Lab View uses. But SignalExpress provides a user interface akin to a traditional instrument rather than the more programmatic approach of LabView.
