Fuse allows you to generate a programming file for your Actel Antifuse devices. Fuse files work with Actel's Silicon Sculptor programmers. (For Axcelerator families, you must use the Silicon Sculptor II programmer.)
In the Tools menu, select Programming File or click the Programming File button in the Design Flow window.
File Type. Select the appropriate file type in the File Type drop-down menu. Select AFM-APS2 if you are using Silicon Sculptor programmer.
Silicon Signature (Optional): Enter a 5 digit hexadecimal value in the Silicon Signature box to identify the design. Valid characters are 0 through 9, and a through f.
Output filename: Designer automatically names the file based on the <design_name>.adb file. You can change the name by entering it in the File Name box. Click Browse to change the directory. Do not add a file extension or suffix to the file name. The Designer software automatically adds the extension to the programming file name when you specify the programming format.
Generate Probe File Also: This option automatically generates a PRB file for use with Silicon Explorer.
Disable clamping diode for unused I/O pins: (SX-A and eX families). Select box to disable clamping diode.
Use the JTAG Reset Pull-up Resistor: (Axcelerator family) Select to enable pull-up resistors on the TRSTB pin (JTAG Reset pin which is active low). This is not part of the JTAG standard but can be useful if you want to make sure that the JTAG tap controller is not reset by mistake if the TRSTB pin is not connected. The pull-up resistor guarantees that if the pin is not driven to low (active), the pin is left in an inactive state (high).
Use the Global Set Fuse: (Axcelerator family) Select to set flip-flops to a known state after power-up. If not selected all flip-flops are set to '0' at power up. If this option is used, all flip-flops are set to '1' at power up.
Click OK when finished to save the file.
