Can I program the Virtex-6 eFUSE bits using iMPACT?
The Virtex-6 eFUSE support in 11.2 is available only on the following conditions:
- Cable being used is the Platform Cable USB II.
- Cable is connected to a USB2.0 high-speed port.
- Cable speed is 6 MHz.
- OS platform is Windows XP 32-bit.
The eFUSE commands will be shown in the iMPACT GUI only if the above conditions are satisfied. When using the batch mode, you will see the following messages displayed (when necessary) to indicate that the above conditions are not met:
- "1': The attached cable does not support eFUSE operations."
- "'1': eFUSE operation is not supported when the cable is connected to a USB 1.0 port. Please connect the cable to a USB 2.0 high speed port and retry the operation."
- "'1': eFUSE operation is not supported on the currently selected cable speed. Please set the cable speed to 6 MHz and retry the operation."
- "'1': eFUSE operation is not supported on this OS platform. It is currently supported on 32-bit Windows XP."
