怎样提升LATTICE FPGA CPLD的下载烧录速度，让FPGA的下载更快更省时间？

Faster program solution

Solution1: 使用威健的下载线，使用vme_usb.exe下载，修改VME文件(其实修改了SVF文件，再转成VME文件，删掉EBR初始化的编程和校验)。
命令如下：

cd C:\ispTOOLS\ispvmsystem\ispVMEmbedded\Version12

vme_usb.exe D:\project\pro_test\test.vme -pa EzUSB-0
修改前编程时间是76秒：

修改后编程时间是49秒：

Solution2: 使用威健的下载线，使用pgrcmd.exe下载，如果需要并行运行多个，需要复制pgrcmd.exe为多份，例如pgrcmd0.exe, pgrcmd1.exe, pgrcmd2.exe。该命令直接调用XCF文件（注：不同的加载程序，对应不同的xcf。也就说要复制多个xcf对应多个工程）。
编程时间是35秒。
命令如下：

cd C:\lscc\Programmer\3.4_x64\bin\nt64

pgrcmd0.exe -infile D:\project\pro_test\test0.xcf
