probably for the decline of many assumptions and analog circuits, so take this difficult and skilled in a variety of disciplines availability -- Analog - IC Design usually lack the resources to market demand. Shortage in the world market further exacerbates this reason, competition dictates of the time-to-market reductions, and analog circuit design, typical of the critical path. As a result, the construction company& 39;s design team in the world, picking from different geographical sites specialized resources where available.
cadence designed to be custom-designed using multiple sites analog IC overwhelming for many years. . For example, I was recently a team has been working to complete uwb communications chip (ultra wideband). The organization assigned a technical lead and program manager (in this man& 39;s administration to take care of all projects), the two teams split design of the site. This is Scotland, we developed a crystal oscillator and high-frequency, low-jitter PLL mode. Simultaneously, we developed countries Maryland fast, folding ADC integrated circuits and the top-level management for other customers states.
the United circuit design block construction of the two groups and the top level Prepare the design cycle later in the parallel. Working in parallel, the design cycle somewhat more stress was essential to meet the market window. It is a normal working hours to help with a different design offices overlapped; days did not need constant daily drawing period to allow for communication sites. Videoconferencing, whiteboard and the ability to share, serving as an excellent medium for discussing circuit design for the design and considering a number of groups customer.
a practical measures multi-site design To ease. High-speed networking around the world to be able to frequently update data between distant team please be patient. Our usual practice is a working library copy of each site and other sites, such as during the night complete, up-to-date database available in both places. Allowed KUROSUSAITODEZAIN review of this step, to ensure compatibility of the interface between blocks, and to provide information on the top floor plan level.
the analog designers to get him to feel it is designed progress. He various parameters to understand how to start and the impact on other specifications, and he is, a lot of relevant information to carry his mind. It is, at best, extremely inefficient to try to time-multiplex circuit development and design team is little, so to adopt this approach. Instead, the parallel circuit can develop better possible.
reusing as analog circuits is becoming more and more important, both to extract value from existing analog and IP (intellectual property) to the initial point of departure provide a new circuit for good. To improve the reuse process, it is useful to define the analog IP standards. We have our work & quot; analog design manual, which covers " the directory structure for the development, including the configuration and version of CAD tools and libraries cell version of the data and processes. Also, the style manual schematic list can be easily recognized side of the circuit designer, as well as signal signal naming names automatically provide the data for as many as possible of one& 39;s function. It takes some overhead to prepare standards and maintain that our experience is that they have very beneficial.
gone day, when using the ANAROGUGURU artistic approach to the possibility of developing a circuit board capacitor inserted here and there was advisable. These days, the integrated products will depend on when the demand for a high level of performance and to maximize the probability that it is important to the best of the first working silicon. More accurate and scientific approach should be, rather than to satisfy his creative work on the bench to watch and is still rewarding product. jefferey gregory
