FAQ’s for Actel’s Antifuse FPGA Programming 29

81. What does the error message “Antifuse xxx, Pulse xxxx, Cannot

program” mean?

Ans. The error message “Antifuse xxx, Pulse xxxx, Cannot program” means that programming of that

particular fuse failed.

82. What does the error message “Antifuse xxxx, Integrity test xxx failed”

mean?

Ans. The error message “Antifuse xxxx, Integrity test xxx failed” means that a specific test failed after

programming xxxx fuses.

Programming failure guideline

All the antifuse devices are expected to have 97% to 100% programming yield. The programming failure

quantity is little higher in a smaller sample size and it varies from lot-to-lot.

Refer to the Programming and Functional Failure Guidelines for additional information on allowable

programming failure quantities for different Actel device families.

If programming failure exceeds the allowable range, contact tech@actel.com before you continue

programming more devices.

Miscellaneous

83. Is there a need for dynamic or static burn-in after programming?

Ans. There is no need for additional burn-in after the units have been programmed. Static and dynamic

burn-in is included in the manufacturing flow for all RadHard/RadTolerant devices.

84. Can 172 CQFP sockets withstand military temperatures (−55°C to

+125°C)?

Ans. The 172-CQFP socket used by Actel for military temperature testing is a custom socket made by

Yamaichi (part number IC51-196-1952). The socket operates in the military temperature range (−55°C to

+125°C).
