FAQ’s for Actel’s Antifuse FPGA Programming 15

33. What is the *.avi/*.txt file? When and where is it generated?

Ans. The *.avi/*.txt file is a log file that is generated when an Actel FPGA is programmed. The file

contains information about the number of VPP voltage pulses applied to program each fuse and the

programming current sensed through each fuse. If a programming failure occurs, the *.avi/*.txt file

contains information about the programming failure mode. A new *.avi/*.txt file is generated each time the

programming sequence begins. If you want to save a *.avi/*.txt file, you must rename it before restarting

the programming sequence. You can find an example and explanation of an *.avi file in the Activator and

APS Programming System - Installation and User's Guide.

The *.avi file is generated by Activator and the *.txt file is generated by Silicon Sculptor. Silicon Sculptor

generates the *.txt file for RadTolerant and RadHard devices only. However, due to some limitations, it

does not generate a .txt file for RTSX/RTSX-S devices.

34. After loading the *.afm file successfully, why am I getting "Unable to

open AFMBLANK file" when I click on Blankcheck in Activator?

Ans. Check if the file <family>.afm exists in the

$ALSDIR/data/a<family>/<family>/<family>.afm directory. If the file does not exist, APSW

gives this message. Uninstall and reinstall the software to resolve this problem.

35. If I program four devices in the Activator’s four sockets, will I get four

different *.avi files for four parts?

Ans. No, you will get only one *.avi file that contains information about all four sockets.

36. Can I still program with *.def and *.fus files on Activator?

Ans. Yes, you can still program Actel FPGAs with the *.def and *.fus files by using the appropriate

method described in the knowledgebase article 1270 (www.actel.com/kb/article.aspx?id=SL1270.)

Currently, Actel Designer tool only generates an *.afm file.

37. Where can I get Silicon Sculptor?

Ans. Silicon Sculptor for Windows is available for download from the Actel website:
