Development Environment and Tools

This section describes the development kit workflow and the associated tools.

3.1

Unpacking the Development Kit

The development kit is delivered as a

.zip

archive containing the project files, source files and doc-

umentation. The first level of the archive contains a

README

file and another archive that is password

protected. By unpacking the password protected archive, the user agrees to the terms of the develop-

ment kit license. Make sure to extract the archive to a directory where the current user has read

and

write permissions.



Important

By unpacking the password protected archive, the user agrees to the terms of the development kit

license.

The extracted archive is organized as follows:

<Extract root>/

constraints/

Contains the constraint files for the design.

documentation/

Contains the documentation for the development kit.

framework/

Contains the files representing the base design along with header files

to interact with the data bus. Apart from the file

config.vh

(see Sec-

tion

3.3.1

, the files in this directory should

not

be modified by the user.

user_logic/

Contains the Verilog source files for the user logic areas.

license.txt

Development kit license file.

devkit.tcl

The Tcl file that is sourced to enable the development kit.



Note

Apart from the file

config.vh

(see Section

3.3.1

, the files in the

framework

directory are not intended

to be edited by the end user.
