SDRAM read-write problem!


I am using XILINX SPARTAN-3 and i have problems on writing and reading from block RAMS connected to kit. I ve read smth. about this subject but it doesn’t explain exactly where i can get an example of SDRAM controller code.

Could anyone help me?

The block RAMs are internal to the FPGA. The external memory is SDRAM.

A sample SDRAM controller is included in the RAMTester sample included with your software installation. Other SDRAM controllers are available online and through Xilinx.
