Hi,
I am facing some problem in the SDRAM data lines. The problems are
whenever I am running more then 115MHz SDRAM read and write test is
failing. I connected logic analyzer to probe the signal then tests are
passing. In PCB SDRAM is placed very close to the ASIC. I do not know
the problem is due to the capacitance or ground. I gave sufficient
ground plane under the device.
If any one knows the solution please help me.
Thanks,
Sankar.K
