Xilinx Foundation Projects

XILINX FOUNDATION is a leading software package for digital systems design, synthesis, and implementation using FPGA and other programmable devices. A central concept is that of a project, which is a file (.pdf) containing information about the circuit(s) such as

• Design Resources, such as which schematic (.sch) files and/or which VHDL (.vhd) files are associated with the complete digital system
• Outputs, such as results of compilation for specific target technologies, netlists in various formats, etc.
• Simulation Resources and outputs, which include netlist files, simulation state (.des) files, and waveform (.tve) files

The Xilinx project for the combinational circuit of Figure 1 we use in this CLAB is called andor. Note: project names must have no more than 8 characters.

Projects consist of many files and directories (folders). For example,

andor.pdf - the top-level project file (essentially a data structure)

andor - the main directory containing many files and directories, including

lib - a directory

xproj - a directory

andor1.sch - source file containing digital schematic diagram

andor1.des - simulation state file

andor1.tve - waveform file

andor.ucf - source file containing pin location specifications

andor.bit - the final binary file that is downloaded to FPGA hardware

numerous other files

In VHDL projects the VHDL source files (.vhd) are included in the main project directory.

In general you will create your own projects, but in this first instance you will download and install the andor project.

1.

Create a directory (e.g. called xilinx) in your home directory. All your Xilinx projects can go in there.

2.

Download the ZIP file andor.zip, and extract it into your xilinx folder:

xilinx

andor.pdf
