Implementing the Design
This chapter describes how to simulate and implement your design containing the
Ethernet 1000BASE-X PCS/PMA or SGMII core.
Pre-implementation Simulation
A functional model of the Ethernet 1000BASE-X PCS/PMA or SGMII core netlist is
generated by the CORE Generator to allow simulation of the core in the design-phase of
the project.
Using the Simulation Model
For information about setting up your simulator to use the pre-implemented model, please
consult the Xilinx Synthesis and Verification Design Guide, included in your Xilinx software
installation.
The model is provided in the CORE Generator project directory.
VHDL Design Entry
<component_name>.vhd
Verilog Design Entry
<component_name>.v
This model can be compiled along with the user’s code to simulate the overall system.
Synthesis
XST - VHDL
In the CORE Generator project directory, there is a <
component_name
>.vho file that is a
component and instantiation template for the core. Use this to help instance the Ethernet
1000BASE-X PCS/PMA or SGMII core into your VHDL source.
After the entire design is complete, create the following:
• An XST project file
top_level_module_name
.prj listing all the user source code
files
• An XST script file
top_level_module_name
.scr containing your required
synthesis options.
To synthesize the design, run
$ xst -ifn top_level_module_name.scr
