Implementing the Example Design

R

2.Run the script that corresponds to your simulation tool using one of the following:

VCS: simulate_vcs.sh

Cadence IUS: simulate_ncsim.sh

ModelSim: vsim -do simulate_mti.do

Implementing the Example Design

After generating the core, the netlists and the example design can be processed using the Xilinx implementation tools. The generated output files include scripts to assist you in running the Xilinx software.

To implement the example design:

Open a command prompt or terminal window and type the following:

Windows

ms-dos>cd <project_dir>\<component_name>\implement ms-dos>implement.bat

Linux

%cd <project_dir>/<component_name>/implement

%./implement.sh

These commands execute a script that synthesizes, builds, maps, and place-and-routes the example design, and then generates a post-par simulation model for use in timing simulation. The resulting files are placed in the results directory and execute the following processes:

1.Removes data files from the previous runs.

2.Synthesizes the example design using either Synplicity Synplify or XST. - The core is instanced as a black box within the example design.

3.ngdbuild. Builds a Xilinx design database for the example design. Inputs:

Part-Package-Speed Grade selection: XC5VLX50T-FF1136-1

Example design UCF:

xilinx_pci_exp_blk_plus_1_lane_ep-XC5VLX50T-FF1136-1.ucf

4.map: Maps design to the selected FPGA using the constraints provided.

5.par: Places cells onto FPGA resources and routes connectivity.

6.trce: Performs static timing analysis on design using constraints specified.

7.netgen: Generates a logical Verilog HDL or VHDL representation of the design and an SDF file for post-layout verification.

8.bitgen: Generates a bitstream file for programming the FPGA.

The following FPGA implementation related files are generated in the results directory:

routed.bit

FPGA configuration information.

routed.v[hd]

Verilog or VHDL functional Model.
