Simulator (ISim) In-Depth Tutorial UG682 (v1.0) April 27, 2009

Preface About This Tutorial About the ISE Simulator (ISim) In-Depth Tutorial The ISim In-Depth Tutorial provides Xilinx PLD designers with a detailed introduction of the ISE Simulator (ISim) software. After you have completed the tutorial, you will have a thorough understanding of how to analyze and debug your design via HDL simulation using ISim. Note: This tutorial is designed for running the ISim software on a Windows environment. Some modifications may be required to run certain steps successfully in other operating systems. Tutorial Contents This tutorial covers the following topics: Chapter 1, “Overview of the ISE Simulator (ISim),” introduces the ISim software environment, including the ISim compilers, linker, simulation executable and Graphical User Interface. Chapter 2, “Using ISE Simulator from ISE Project Navigator,” explains how to launch a functional simulation through the ISE Project Navigator software. Chapter 3, “Running ISE Simulator (ISim) Standalone,” guides you through a typical procedure for launching a functional simulation using the ISim compiler, linker and simulation executable outside of the ISE Project Navigator environment. Chapter 4, “Using ISE Simulator (ISim) Graphical User Interface,” introduces you to the ISim GUI by examining, debugging, and verifying a functional simulation. Tutorial Flows This tutorial presents two flows in which ISim can be used for performing a functional (Behavioral) simulation. • Using ISim from ISE® Project Navigator • Using ISim Standalone Using ISim from ISE Project Navigator In this flow you will launch ISim via one of the simulation processes available in the ISE Project Navigator. This flow works best when an ISE Project Navigator project is created in order to implement the design in a Xilinx® FPGA or CPLD. This flow is useful when your design involves sources that are not HDL (schematics, cores, etc.) and requires Project Navigator to properly convert these sources to HDL source files which ISim can compile.

Additional Resources Follow these chapters if you are interested in this flow: • Chapter 1, “Overview of the ISE Simulator (ISim),” • Chapter 2, “Using ISE Simulator from ISE Project Navigator,” • Chapter 4, “Using ISE Simulator (ISim) Graphical User Interface,” Using ISim Standalone In this mode you will primarily simulate your design by creating your own ISim project files and running the HDL linker and simulation executable in a command line or batch file mode. This flow is useful for users not using Project Navigator to manage their HDL design. The following chapters will help you understand this flow: • Chapter 1, “Overview of the ISE Simulator (ISim),” • Chapter 3, “Running ISE Simulator (ISim) Standalone,” • Chapter 4, “Using ISE Simulator (ISim) Graphical User Interface,” Additional Resources To find more detailed information and discussions on ISE Simulator (ISim) topics covered in this tutorial, refer to the following documents: • ISim Help is available from the ISim software. • ISim User Guide, accessible from the Software Manuals page on the Xilinx website: http://www.xilinx.com/support/documentation/sw_manuals/xilinx11/plugin_ism.pdf • Software Manuals: To find additional documentation, see the Xilinx website at: http://www.xilinx.com/literature To search the Answer Database of silicon, software, and IP questions and answers, or to create a technical support WebCase, see the Xilinx website at: http://www.xilinx.com/support To discuss topics of interest with other Xilinx users, see the Xilinx User Community Forum at: http://forums.xilinx.com/xlnx/ viii www.xilinx.com ISE Simulator (ISim) In-Depth Tutorial UG682 (v1.0) April 27, 2009
