These are the design files for the dualport module that attaches to the
SDRAM controller core and the surrounding application that uses the core
to test the SDRAM on the XESS FPGA boards.
You can find application notes about the dualport module at

The content of each subdirectory is listed below.
* XS_LIB
This directory stores the VHDL files for all cores that are
applicable to all models of XESS FPGA boards. This includes the
dualport module and the SDRAM controller core.
* XSA
This directory stores all the project directories for all the models
of XSA Boards.
* XSA_LIB
This directory stores the VHDL files for all cores that have been
customized for the XSA Boards. This includes the core for testing
the SDRAM.
* 50, 100, 200, 3S1000
Each of these directories stores the project directories for a
particular model of XSA Board: XSA-50, XSA-100, XSA-200 or
XSA-3S1000.
* XSB
This directory stores all the project directories for all the models
of XSB Boards.
* XSB_LIB
This directory stores the VHDL files for all cores that have been
customized for the XSB Boards. This includes the core for testing
the SDRAM.
* 300E
Each of these directories stores the project directories for a
particular model of XSB Board: XSB-300E.
* test_dualport:
This directory contains a test_dualport.vhd file that instantiates
the dualport module and SDRAM test module for a particular model of
XESS FPGA board. The test_dualport.ucf file stores the appropriate
pin assignments for the board. The test_dualport.npl file allows you
to rebuild the application using WebPACK. The resulting
test_dualport.bit file can be downloaded to the FPGA board to test
the dualport access to the SDRAM.
