Hi,

Thank you for your reply. Actually, what I want to know is the meaning of values after the C or R letter. When I read the handbook of Cyclone5 or Cyclone 10 GX FPGA, I find approximately the same diagram. The difference is in the incterconnect. For example:

  • Arria 10 : C4, C27
  • Cyclone 5 : C2/C4, C12
  • Stratix 10 : C2/C3/C4, C16

So, are these values related to the interconnects technology, speed or width...?

Regards,

Lotfi.
