Table 24-1:Data2MEM Command Line Options

Option

Description

 

 

–ouvhm filename

The -o option specifies the name of the output files. The string

 

preceding the file name indicates which file formats are to be

 

output. No spaces can separate the specified file types, and

 

file types can appear in any order. One or more file types can

 

be specified. The file type are:

 

'u' - specifies a UCF file format, with a .ucf file extension

 

'v' - specifies a Verilog file format, with a .v file extension

 

'h' - specifies a VHDL file format, with a .vhd file extension

 

'm' - specifies a MEM file format, with a .mem file extension

 

The filename applies to all specified output file types. If the file

 

extension is missing, the appropriate file extension will be

 

added to the output files.

 

 

–ppartname

Specifies the name of the target Xilinx part. If unspecified, a

 

XCV50 part is assumed. To view a list of supported parts, use

 

the -h support option.

 

 

–ppfilename

The -pp option specifies the name of an input preprocess file.

 

If a filename is not specified, a .bmm file extension is assumed.

 

If this option is specified with the -o option, the preprocessed

 

output is sent to the specified output file. Otherwise,

 

preprocessed output is displayed on the console.

 

 

–qewi

The -q option reduces the output of Data2MEM messages.

 

Message type arguments are:

 

'e' - disables ERROR messages

 

'w' - disables WARNING messages

 

'i' - disables INFO messages.

 

 

–u

The -u option updates the text output files, specified with the

 

-o option, for all address spaces. Depending on the file type,

 

an output file is either empty, or will contain initializations of

 

all zero. If this option is not used, only address spaces that

 

receive transformed data are output.

 

 

–woffon

The -w option prevents or allows file overwrites. Specifying

 

this option with the off argument directs Data2MEM to output

 

an error if a file will be overwritten. Using this option with the

 

on argument allows Data2MEM to overwrite files without

 

issuing a warning message. By default this option is on.

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.
