In the design and implementation of high precision time interval of FPGA system

为了解决传统时间间隔测量系统设备体积大、测量精度低、测量范围窄的缺点,文章提出了基于FPGS高精时间间隔测量系统的实现方法。此系统的核心是FPGA,有其完成信号的处理和控制。使用的基本测量原理是非门延迟线法。FPGA系统主在QuartusⅡ环境下通过硬件描述语言进行设计。测试结果表明,此系统具有测量精度高、可靠性强的优点。具有广阔的实用价值和市场空间。

In order to solve the traditional time interval measurement system devices are bulky, low accuracy, measurement range narrow shortcomings, the paper proposes a method based on FPGS high-precision time interval measurement system. This system is the core of FPGA, and the processing is completed with the control signal. The basic measuring principle is non-gate delay line method to use. In the main FPGA system design environment Quartus Ⅱ by hardware description language. The test results show that this system has high accuracy and reliability advantages. Has broad practical value and market space.
