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。
Many CAD users dismiss schematic capture as a necessary evil in the process of creating\r\nPCB layout but we have always disputed this point of view. With PCB layout now offering\r\nautomation of both component placement and track routing, getting the des
