Hello everybody,
I'm actually using SDRAM Controller Core for my project at 110Mhz to drive the SDRAM chip. The user Guide UG-01085 specify PC100 for this IP.
Is that ok tu use it at 110Mhz? And upgrade at 135Mhz after this?
Best Regards,
A

HI,
If you refer to attached screenshot from UG-01085 FIgure 96, I can see there are 2 clk in the pic.
I presume you are referring to "SDRAM clock" connected to the SDRAM chip ?
Since this is clock used by the SDRAM chip and not by FPGA, I suggest you to check up the SDRAM datasheet to find out about the supported clock tolerance info or perhaps you can also consult the SDRAM chip vendor directly.
Thanks.
Regards,
dlim
