You can use the default settings or choose from the available options in the drop-down menus. You can also browse for a specific device using the Device Details button.
After setting up your project parameters, you need to choose the preferred language and synthesis tool for your design. You can select VHDL, Verilog or Schematic as your design entry method. You can also select XST (Xilinx Synthesis Technology) or a third-party synthesis tool as your synthesis tool. You can use the default settings or change them according to your preferences.
After choosing your language and synthesis tool, you need to add sources to your project. You can add existing sources from your computer or create new sources using the ISE tools. You can also specify the design hierarchy and the top-level module of your design. You can use the default settings or modify them as needed.
After adding sources to your project, you need to add constraints to your design. Constraints are rules that specify how your design should be implemented on the target device. You can add timing constraints, physical constraints and other constraints using the ISE tools. You can use the default settings or create your own constraints files.
After adding constraints to your design, you have completed the New Project Wizard and created a new project for your design. You can see your project files and settings in the Project Navigator window.
Step 5: Create an HDL Source
If you chose VHDL or Verilog as your design entry method, you need to create an HDL source file for your design. You can do this by clicking on Project > New Source or by using the shortcut Ctrl+N. This will open a New Source Wizard that will help you create a new source file.
You need to select an HDL Module as your source type and enter a file name and a description for your source file. You also need to specify the entity name and the port names and directions of your module. You can use the default settings or enter your own values.
After creating a new source file, you will see an HDL editor window where you can write your HDL code for your design. You can use the syntax highlighting, auto-completion and error-checking features of the editor to help you write your code. You can also use the templates and examples provided by the ISE tools to guide you through common design tasks.
After writing your HDL code, you need to save your source file by clicking on File > Save or by using the shortcut Ctrl+S. This will add your source file to your project and update the design hierarchy accordingly.
Step 6: Design Simulation
After creating an HDL source file for your design, you need to verify its functionality and performance using simulation. Simulation allows you to test your design before implementing it on the target device. You can use the ISE Simulator (ISim) tool to perform simulation on your design.
ISim is a mixed-language simulator that supports VHDL and Verilog. It also supports native simulation of all AMD hard IP blocks, such as PPC, MGT, PCIe, etc. It does not require any special license or additional mapping or compilation steps. It also offers various features and options to help you debug and optimize your design, such as waveform tracing, waveform viewing, HDL source debugging, power analysis, memory editor, etc.
To perform simulation on your design using ISim, you need to follow these steps:
Select your source file in the Project Navigator window and click on Simulate Behavioral Model or Simulate Post-Route Model depending on the level of simulation you want to perform.
This will launch the ISim GUI where you can see your design hierarchy, source files, waveforms and console.
You can use the toolbar buttons or the menu commands to control the simulation flow. You can also use Tcl commands or scripts to automate the simulation process.
You can add signals to the waveform window by dragging them from the design hierarchy or by using the Add To Waveform command.
You can use the cursor tools or the zoom tools to navigate and analyze the waveform data.
You can use the breakpoint tools or the step tools to pause and resume the simulation execution.
You can use the force tools or the memory editor tools to modify the signal values during simulation.
You can use the probe tools or the watch tools to monitor the signal values during simulation.
You can use the power tools or the SAIF tools to estimate and optimize the power consumption of your design.
You can use the source debugging tools or the code coverage tools to debug and improve your HDL code.
After performing simulation on your design using ISim, you can save your simulation results and settings by clicking on File > Save Project or by using the shortcut Ctrl+S.
Step 7: Implement Design and Verify Constraints
After verifying your design using simulation, you need to implement it on the target device using the ISE implementation tools. Implementation is the process of translating your design into a configuration file that can be downloaded to the device. It involves three main steps: synthesis, mapping and place and route.
Synthesis is the process of converting your HDL code or schematic into a netlist of logic elements and connections. You can use XST or a third-party synthesis tool to perform synthesis on your design.
Mapping is the process of mapping the logic elements in your netlist to the physical resources available on the device. You can use the MAP tool to perform mapping on your design.
Place and route is the process of placing and connecting the mapped resources on the device. You can use the PAR tool to perform place and route on your design.
To perform implementation on your design using the ISE implementation tools, you need to follow these steps:
Select your source file in the Project Navigator window and click on Implement Design or use the shortcut Ctrl+I. This will launch the Process Properties window where you can set various options and parameters for each implementation step.
You can use the default settings or customize them according to your preferences. You can also use the SmartXplorer tool to run multiple implementations with different settings and compare the results.
After setting up your implementation options, click on OK to start the implementation process. You can see the progress and status of each step in the Console window.
After completing the implementation process, you can see the implementation results and reports in the Project Summary window. You can also view the device utilization, timing summary, power summary and other information in the Design Summary window.
You can also view and edit your implemented design using various tools, such as Floorplanner, FPGA Editor, Timing Analyzer, etc.
After implementing your design using the ISE implementation tools, you need to verify that your design meets your timing and physical constraints. Constraints are rules that specify how your design should be implemented on the device. You can use the ISE constraint tools to verify your constraints on your design.
Timing constraints are rules that specify the timing requirements of your design, such as clock frequencies, input/output delays, setup/hold times, etc. You can use the UCF (User Constraints File) editor or the PlanAhead tool to create and edit timing constraints for your design. You can also use the Timing Analyzer tool to check and analyze the timing performance of your design.
Physical constraints are rules that specify the physical characteristics of your design, such as pin locations, I/O standards, voltage levels, etc. You can use the UCF editor or the PlanAhead tool to create and edit physical constraints for your design. You can also use the Floorplanner tool or the FPGA Editor tool to view and modify the physical layout of your design.
To verify your constraints on your design using the ISE constraint tools, you need to follow these steps:
Select your source file in the Project Navigator window and click on User Constraints or use the shortcut Ctrl+U. This will launch the UCF editor where you can see and edit your existing constraints or create new ones.
You can use the syntax highlighting, auto-completion and error-checking features of the editor to help you write your constraints. You can also use the templates and examples provided by the ISE tools to guide you through common constraint tasks.
After editing or creating your constraints, you need to save your UCF file by clicking on File > Save or by using the shortcut Ctrl+S. This will update your project files and settings accordingly.
You can also use other constraint tools such as PlanAhead, Timing Analyzer, Floorplanner or FPGA Editor to view and edit your constraints in different ways.
