28 FAQ’s for Actel’s Antifuse FPGA Programming

76. Concerning the programming file *.afm, is there a way of incrementing

the silicon signature without redoing place-and-route?

Ans. There is no way of incrementing the silicon signature without regenerating the *.afm file. However, it

is not necessary to run place-and-route again.

77. Are all the fuses checked by Silicon Sculptor?

Ans. Each fuse is checked individually as the array is programmed. After all array fuses are programmed,

a series of additional "net shorts" tests are performed to verify that no additional fuses have been

programmed. Checksum fuses are programmed after the net shorts tests are performed.

78. What does EIT test mean?

Ans. EIT stands for Enhanced Integrity Test. It is one of the final programming tests performed to check

the integrity of the un-programmed antifuses in the device.

79. What is the reason of getting "Bad device id" during programming?

Ans. This error occurs mostly due to bad contact. Clean the socket module with a blower. Also, check the

leads of the devices. Sometimes, due to the oxidation, the leads cannot make good contact with the

module. RoHS devices cannot be in open ambient for more than a day, otherwise they will oxidize

quickly.

Another reason could be due to broadcasting in multisite programmer: if you have devices from one UMC

in a master site and devices from MEC in the other sites, or vice versa, this will result in this error. This

applies to SXA devices only.

80. What does “Function aborted” during programming mean?

Ans. You should not get this error message. This message appears during programming actions if the

user stops the action by pressing ESC or Cancel. To avoid this inadvertent situation, set the programmer

configuration to Novice Mode (File/Configuration). In this case, any user interruption will be prompted with

a confirmation pop-up window.
