体域网基带验证平台设计与实现

Design and implementation of the verification platform for WBAN Baseband

测试验证是SoC设计过程中的重要步骤,针对穿戴式体域网基带SoC在验证中的测试向量复杂、射频可靠性要求高、结果多样化等挑战,设计并实现了体域网基带测试验证平台。在硬件设计上,采用高集成度FPGA(Altera Cyclone Ⅲ)、射频芯片(MAX2837)和混合信号前端芯片(MAX19712),提高了系统的可靠性;在软件上,设计了体域网数据流状态机,对体域网基带自动加载多种速率的数据流,验证其对多种健康信息的服务质量(QoS)。该验证平台已经针对自主开发的IEEE802.15.6基带进行了大量的测试验证工作,主要指标满足体域网基带芯片的验证需求,同时也可以扩展应用到其他近距离无线通信芯片的设计验证应用中。

Verification test is an important step in the design process of the SoC. To solve the questions happened in the verifica-tion of the wearable Wireless Body Area Network（ WBAN） baseband SoC, such as vector complex, high reliability of RF and results diversification,this paper designed and implemented a WBAN baseband verification platform. In the hardware,highly integrated FPGA（ Altera- Cyclone Ⅲ）, RF chip（ MAX2837） and mixed- signal front- end chip（ MAX19712） were used to Improve the reliability of the system. In the software, a WBAN ′ s data stream state machine was designed to load multi- rate data stream automatically, and veri-fy the Quality of Service（QoS）. Currently, the platform accomplished a large number of test validation for the IEEE 802. 15. 6 base-band system which is developed independently by ourselves. The key indicators meet the needs of WBAN chip design verification,and also can be extended to verify other short- range wireless communication chips.
