How about the HSSICR2REFCLKDIVIDER

1SM21BHU2F53E2VG，客户在使用quartus pro 19.3 客户希望在一个 H tile的24个收发器中实现12个单独发送，每个发送速率都不一样，编译的时候发现发送模块好像都调用了HSSICR2REFCLKDIVIDER 这个东西 不知道是干什么用的 发现一个H tile里面24个收发器里只有8个这模块，如果要每路的发送时钟都是独立，做发送的时候能绕开这个模块吗 否则应该怎...

HI,

I don't think I saw this "HSSICR2REFCLKDIVIDER" in the user guide doc

May I know where do you see this block as I suspect it could be some internal block generated or process by Quartus in background processing ?

Typically what matter is the setting in the NativePHY IP.

  • As long as user key in the correct setting in NativePHY IP as per their design requirement then it's fine.
  • Quartus synthesis and fitter compilation will review the input setting from user and generate some internal processing in background.
  • User doesn't need to care for these background processing by Quartus. These internal block are used for Quartus compilation process only and doesn't affect user design functionality.

Thanks.
