1 What is IP-XACT?
IP-XACT is an XML format that defines and describes electronic components and their designs. IP-XACT was created by the SPIRIT Consortium as a standard to enable automated configuration and integration through tools. The goals of the standard are to ensure delivery of compatible component descriptions from multiple component vendors, to enable exchanging complex component libraries between electronic design automation (EDA) tools for SoC design (design environments), to describe configurable components using metadata, and to enable the provision of EDA vendor-neutral scripts for component creation and configuration (generators, configurators). Approved as IEEE 1685-2009 on December 9, 2009, published on February 18, 2010.
2 有哪工具支持？
Vivado, ARM Socrates etc.
3 IP-XACT就是解决目前在SOC系统设计中的IP集成问题。从图中可以看出IP的支付费用在不断地增长，在ＳＯＣ设计中占据的比重也越重要。
