本文:采用了FPGA方法來模擬高動(dòng)態(tài)(Global Position System GPS)信號(hào)源中的C/A碼產(chǎn)生器。C/A碼在GPS中實(shí)現(xiàn)分址、衛(wèi)星信號(hào)粗捕和精碼(P碼)引導(dǎo)捕獲起著重要的作用,通過硬件描述語言VERILOG在ISE中實(shí)現(xiàn)電路生成,采用MODELSIM、SYNPLIFY工具分別進(jìn)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.
