hi,
When I am writing to sdram through synopsys designware memory controller the address is not being
properly latched by the SDRAM. Like, if I give address as 0x0018 it will write to
0x0010(one of the address lines is not properly latched). I checked the data sheet
of the SDRAM (Micron 48LC32M16A2) and the setup time is given as 2.8 ns.But, I am giving
the same clock which I gave to the memory controller. Have anybody used synopsys Designware
memory controller to write to SDRAM. If yes, is it the same clock that we give to
both the memory controller and SDRAM or shall the clock to SDRAM to be delayed by
some time from the clock given to memory controller.
Thanks,
gangi.
