R

instance_name specifies the name of the instance you wish to know the available processes for.

Example:

% project get_processes [-instance Inst_dcm1]

 

 

Description:

In this example, the project get_processes command is used to list all

 

of the available processes for only the instance, Inst_dcm1.

 

 

Tcl Return:

The available processes as a text string. In this example, a list of

 

processes for Inst_dcm1 is returned.

 

 

new (create a new ISE project)

The project new command creates a new ISE project.

% project new <project_name>

project is the name of the Xilinx Tcl command.

new is the name of the project subcommand.

project_name specifies the name for the ISE project you wish to create.

Example:

% project new watchver.ise

 

 

Description:

In this example, a new ISE project named watchver.ise is created in

 

the current directory.

Tcl Return:

The name of the new ISE project.

open (open an ISE project)

The project open command opens an existing ISE project. If the project does not exist, an error message to create a new project with the project new command appears.

% project open <project_name>

project is the name of the Xilinx Tcl command.

open is the name of the project subcommand.

project_name specifies the name for the ISE project you wish to open.

Example:

% project open watchver.ise

 

 

Description:

In this example, the watchver.ise project in the current directory is

 

opened.

Tcl Return:

The name of the open ISE project.

8.2i specifications

Xilinx 8.2i is a significant version of the Xilinx ISE (Integrated Software Environment) that emerged in the early 2000s, marking an important milestone in the world of FPGA (Field-Programmable Gate Array) development. This version introduced a slew of advanced features, technologies, and characteristics that made it an indispensable tool for engineers and developers in designing, simulating, and implementing digital circuits.

One of the standout features of Xilinx 8.2i is its enhanced design entry capabilities. This version supports multiple design entry methods, including schematic entry, VHDL, and Verilog HDL, giving engineers the flexibility to choose their preferred approach. The integrated environment provides user-friendly graphical interfaces, making it accessible for both novice and experienced users.

Xilinx 8.2i's synthesis tools have been improved to enable more efficient design compilation and optimization. The new algorithms used in this version facilitate faster synthesis times while reducing power consumption and improving performance. Furthermore, it features support for advanced FPGA architectures, which allows for the implementation of more complex designs with greater efficiency.

The implementation tools in Xilinx 8.2i include advanced place and route capabilities, utilizing state-of-the-art algorithms for optimized resource usage. These tools enable designers to make better use of FPGA resources, ensuring that designs fit within the constraints of the target device while maximizing performance.

Another key characteristic of Xilinx 8.2i is its extensive support for various Xilinx devices such as the Spartan, Virtex, and CoolRunner series. This compatibility ensures that developers can leverage the powerful features of these FPGA families, including high-speed transceivers and DSP slices.

Xilinx 8.2i also places a strong emphasis on simulation and verification. The version integrates with various simulation tools, allowing for thorough testing of the designs before implementation. This reduces the risk of errors and ensures that the final product meets specifications.

In addition, this version includes support for design constraints, enabling engineers to specify timing, area, and other critical design parameters. By accommodating constraints, Xilinx 8.2i helps in achieving reliable and efficient designs tailored to project needs.

In summary, Xilinx 8.2i is a robust software development tool that enhances the design process for FPGAs. Its comprehensive features, including multiple design entry options, advanced synthesis and implementation tools, extensive device support, and strong simulation capabilities, make it a valuable resource for engineers and developers striving for innovation in digital design.
