7. Click the Browse... button. The Save As dialog appears.
8. Browse to the destination folder, specify a file name, and click Save.
9. Click OK. After a few moments the JEDEC programming file is output.
10. See the Programming with PAC-Designer section of this document for details on downloading a programming
file to the board.
Programming the ispClock5400D Evaluation Board with PAC-Designer
To restore the ispClock5406D to factory settings or load an alternative demo design, use the procedure in this sec-
tion to reprogram the evaluation board using PAC-Designer software.
Programming for the ispClock5406D device is controlled using PAC-Designer or the ispVM System software, avail-
able for download from the Lattice website at www.latticesemi.com/ispvm. Refer to the ispVM System software for
help regarding operation of this software.
JTAG programming is supported with the eight-pin connector J14 and either the Lattice ispDOWNLOAD USB
download cable (HW-USBN-2A, provided) or the parallel download cable (HW-DLN-3C). PAC-Designer provides
an interface to configure the ispClock5406D and can be used to either directly program the evaluation board or to
export a JEDEC • le which can be used with ispVM to program the evaluation board.
The board must be un-powered when connecting, disconnecting, or reconnecting the ispDOWNLOAD Cable.
Always connect the ispDOWNLOAD Cable's GND pin (black wire) before connecting any other JTAG pins. Failure
to follow these procedures can in result in damage to the ispClock5406D device and render the board inoperable.
Connecting Programming Cable and a Power Source
To connect the ispClock5400D Evaluation Board to your PC:
1. Plug the ispDOWNLOAD Cable into the USB port on the PC.
2. Plug the JTAG color-coded wires of the ispDOWNLOAD cable in the order marked on the board's JTAG inter-
face header (J14) before applying power. The cable comes with an 8-pin adapter for 1x8. This will allow you to
maintain the order and simplifies moving it to other ports.
3. Plug the power cord in and insert the connector into the Power Jack (J13).
Once the board is powered up, you will see the green LED labeled POWER. This LED is lit when the AC
adapter is plugged in or if the board is powered by the +12V red and black banana receptacles.
Set up the Programming Cable Interface
To setup the ispDOWNLOAD cable interface:
1. Run PAC-Designer.
2. Choose Options > Cable and I/O Port Set-up.
The Cable and I/O Port Setup dialog appears.
3. From the Programming Cable Interface section, click the Change... button.
The Change Programming Cable Interface dialog appears.
