Using the Xilinx Software

This chapter describes how to process your System Generator design with the Xilinx downstream software tools. Sections in this chapter are:

∙Xilinx ISE 4.1i Project Navigator

∙Using an EDIF software flow

∙Simulation

∙Xilinx software tools resources

Xilinx ISE 4.1i Project Navigator

During code generation, the System Generator creates several project files for use in Xilinx and partner software tools. One is for the Xilinx 4.1i ISE Project Navigator tool. By opening this project file, you can import your System Generator design into the Project Navigator, and from there, you can synthesize, simulate, and implement the design in the Xilinx 4.1i software tools environment.

This file is called <name of project>.npl. We will use the name my_project.npl for the following discussion.

Opening a System Generator project

You may double-click on your .npl file in Windows Explorer. The Project Navigator file association with .npl will cause Project Navigator to launch, opening your my_project.npl System Generator design project.

You may also open the Project Navigator tool directly, then choose File >> Open Project from the top level pulldown menu. Browse to the location of your System Generator my_project.npl and open it.

Customizing your System Generator project

When first opening your System Generator project, you will receive a warning indicating that you have not set up a device package. This is because System Generator did not require that you enter a device package before generating VHDL. You may now configure the rest of your Xilinx design by opening the Project
