20 FAQ’s for Actel’s Antifuse FPGA Programming

44. Can I use BPWin to program Actel devices?

Ans. No. You need to use Silicon Sculptor (SculptW) to program Actel devices. Although Actel devices

are supported in BPwin, sometimes specific fixes are not available in BPwin. If you use BPwin to program

an Actel device and encounter programming failure, contact tech@bpmicro.com.

45. Is the *.avi/*.txt file supported in Silicon Sculptor?

Ans. The *.txt file is supported in Silicon Sculptor only for RadTolerant and RadHard devices. No *.txt file

is supported for RTSX/RTSX-S devices.

46. Why am I getting a five digit checksum (example: CSUM=7EA7C) under

“Data Pattern” when I load an *.afm file in the ScultpW?

Ans. This checksum is not related to an Actel device or an Actel *.afm file. The BP software calculates

this number for other use. There is no need to worry about this as it is not related to Actel.

47. In Silicon Sculptor, under Device > Option, I see two other options:

"secure after programming" and "secure after verifying". What is the

difference between these two options?

Ans. Secure After Programming is the option we use for Actel devices. Secure After Verifying is used

for EPROM devices. BP uses the same interface for the Actel software and the BP software. Selecting

Secure After Verifying does not do anything to Actel devices. If you want automatic secure, use the

Secure After Programming option.

48. What are the functions of the Blankcheck and Checksum commands in

the software?

Ans. The Blankcheck button or menu command executes a test to determine if a device has already

been programmed. Blankcheck is performed automatically before the chip is programmed or when the

command is executed. Executing Blankcheck results in either “blank” or “not blank”, followed by the

silicon signature, checksum, and security fuse status read from the device. Only blank devices of the

correct type (according to the design parameters) result in a blank status.
