改进的IP可重用性评估程序

The Amelioration of IP Reusability Evaluation Program

随着IP在设计中重用的次数和比例不断增加,工业界需要有一种客观、有效的可重用性评估方法。一方面,IP用户可以利用它从第三方供应商提供的众多同类型IP中选择合适、高可重用性的产品,从而最大程度的降低设计成本和风险;另一方面,开发者也必须对IP做出评估,并通过不断改进设计方法学达到提高产品质量的目的。本文在对国际通用的IP可重用性评估程序OpenMORE和QIP分析的基础上,针对其中存在较大的“主观误差”问题提出了改进的方法,改进后的方法较之现有方法在评分和权值设定等方面有了较大的改善。

As the reuse times and scale of IPs in design are increased, an objective and efficiency reusability evaluation methodology is needed. On one hand IP users can select appropriate and high reusable products in the IPs library so that they can reduce the design cost and risk greatly; on the other hand IP providers also need evaluate the reusability of IPs so that they can improve the product quality by continuous improving design methodology. This paper analyses OpenMORE and QIP, which both are the popular reusability quality evaluation systems, and presents an improvement method according to the shortcoming in subjective errors. Improvement methodologies are improved in grade and weigh enactment greatly.
