摘要
提出了一种IRIG-B(DC)码产生电路的设计方法。采用Altera公司低功耗Cyclone FPGA系列中的EP1C6T144、8段数码管、晶体振荡器和MAX3232E等器件构成硬件电路、使用VHDL语言设计IRIG-B直流时间码的软件。为了设置和观察,使用8段数码管、拨码开关和按键来显示、修改和设置天、时、分、秒等时间信息。仿真和试验结果表明,该设计可以产生标准的IRIG-B(DC)码时间脉冲序列。
In this paper,a method of IRIG-B (DC) time code generate circuit is presented. The circuit uses such as EP1C6T144 of Altera Cyclone FPGA,8-segment numeric LED,crystal oscillator and MAX2323E.,VHDL is used as the develop language to program the software. To modify and display time information as day, hour, minute and second, 8-segment numeric LED,DIP switch and buttons are used. The consequence of simulations and experiments show that the design can generate the standard IRIG-B(DC)code time pulse sequence.
