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 否则应该怎么做12个发送呢?

HI,
I don't think I saw this "HSSICR2REFCLKDIVIDER" in the user guide doc
- https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/stratix-10/ug_stratix10_l_htile_xcvr_phy.pdf
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.
Regards,
dlim

HI,
I don't hear back from you after my feedback explanation.
Hopefully I clear your doubt.
For now, I am setting this case to closure.
Thanks.
