本文:采用了FPGA方法來模擬高動態(Global Position System GPS)信號源中的C/A碼產生器。C/A碼在GPS中實現分址、衛星信號粗捕和精碼(P碼)引導捕獲起著重要的作用,通過硬件描述語言VERILOG在ISE中實現電路生成,采用MODELSIM、Synplify工具分別進行仿真和綜合。
One of the strengths of Synplify is the Finite State Machine compiler. This is a powerfulfeature that not only has the ability to automatically detect state machines in the sourcecode, and implement them with either sequential, gray, or one-hot encoding. But alsoperform a reachability analysis to determine all the states that could possibly bereached, and optimize away all states and transition logic that can not be reached.Thus, producing a highly optimal final implementation of the state machine.
