基于FPGA的可重构信号发生器
Re-Configurable Signal Generator Design Based on Field Programmable Gate Array
【摘要】 信号发生器在动态测试领域有重要应用。借鉴电子设计自动化EDA领域的可重构思想,以现场可编程门阵列FPGA为载体,对信号发生器的开放式体系架构进行了试验研究。所设计的信号发生器具有参数易调节与小尺寸低功耗等特点,可方便下载地震波或路面载荷等现场信号,从而为结构动态测试提供参考激励。进行了压电悬臂梁激振试验,验证了设计方法的可行性。
【Abstract】 Based on FPGA(Field Programmable Gate Array) chip,a re-configurable signal generator with open-architecture was developed.The design flow on the Quartus II platform with lower power and small volume was presented.The earthquake wave acquisitioned in field condition could be downloaded into the FPGA chip as referenced signal for structure dynamic experiments.A piezoelectric beam excited experiment was presented.The experiment results show that the reliability and precision of the signal generator is satisfied.
