Saving a Modified Chain
If you use a previously saved chain description as a template for
creating another chain description, or want to modify a description
and save it under another name, use the Save As command.
This will bring up the CDF File Operation menu. To name your
file, use the mouse to highlight the asterisk (*) on the File Name
line, then type in the name you want and click once on OK.

Data Security Selection

Any Xilinx device selected for programming can be secured with the
Data Security (DS) or Data Protection (DP) or both.
When enabled, Data Security disables reading the programmed
contents of a device (the man.id and signature remain readable).
Data Protection allows only the reading of the programmed
data. The device contents cannot be altered.
When both Data Security and Data Protection are enabled,
the device can be neither read nor re-programmed.
To enable Data Security or Data Protection or both:
1.
2.

File Save As
Find the DS and DP checkboxes in the Chain Description. They
should only appear in rows in which programming is involved
(Program, P & Verify, and P & V & Test).
Enter a check in either or both boxes by clicking once on the box.
If you change your mind about security, click once on the box
again. The check will disappear.
