22 FAQ’s for Actel’s Antifuse FPGA Programming

Programming Files and Functions

52. What files can I use to program a device?

Ans. For details on the files that you can use to program a device, see Table 4: below:

Table 4: Files for Programming

Activator

Silicon Sculptor

*.adb or *.afm file

*.afm file

53. Can I generate * .afm files from *.def and *.fus files?

Ans. Yes, it is possible to generate *.afm files from *.def and *.fus files. Refer to Knowledgebase article

1270 (www.actel.com/kb/article.aspx?id=SL1270) for more information.

54. What does AFM stand for?

Ans. AFM stands for Actel Fuse Map (programming file type for antifuse devices only).

55. Can I read back the design content from a programmed FPGA to make a

copy of the same design?

Ans. No, you cannot read back design content from a programmed antifuse device.

56. Why does the log file say that the size of the file is zero when I load the

*.afm file?

Ans. The *.afm file is corrupted. Regenerate the *.afm file and compare with the existing one. Also

compress (Zip) the file before transmitting from the host PC.

57. I get the following error message when loading my *.afm file into

SculptWin: “bad data format in data file”. “Expected header code of 70,

received code 3C and cannot program”. How can I resolve it?

Ans. This error message is generic and does not refer to the header. The *.afm file is corrupted and must

be regenerated.
