摘要
介绍了基于FPGA的某型空管应答机高度源信号模拟器的电路设计过程,主要包括飞机高度数据的编码和格式、系统硬件结构和工作流程以及FPGA功能模块设计和VHDL编程实现等,并通过了Active HDL 6.1的仿真验证。提出的数据转换算法节约了FPGA芯片资源,转换速度快,延时小。系统功能改进和升级十分方便,稳定性好、可靠性高、成本低廉。
The circuit design of simulated altitude source for certain air - control transponder based on FPGA is introduced. Including airplane altitude code and data format, system hardware structure, workflow, design of FPGA functional module and program,Active HDL 6.1 - based simulation proof are presented. The data conversion algorithm with high transition rate and low time delay reduces FPGA resource. The system with high stability,high reliability and low cost is easy to improve or upgrade.
