Information about converting PDB file to JAM STAPLE for ACTEL

devices

Actel PDB file is a proprietary file format that can be supported by Actel programmers only,

e.g. FlashPro programmer. PG4UW control program can program Actel devices only with Jam

STAPL file. Therefore a file conversion between PDB and STAPL is necessary.

Converting PDB file to Jam STAPL file for ACTEL devices:

 install software tool FlashPro (component of Actel Libero tool suite or can be downloads

from www.actel.com

as a standalone version)

 run FlashPro

 click the New Project button or from the File menu choose New Project and type in the

name of your project in the Project Name field. Select desired programming mode – single

device or chain and click OK

 from the Configuration menu, choose Load Programming File and select corresponding

*.pdb file to convert

 from the File menu, choose Export/Export Single Device STAPL File... Type in file name

and click Save button for export STAPL file to the directory you specified

 Conversion of PDB file to STAPL has finish and created *.stp file can be used for

programming Actel device.

Frequently asked questions about Actel

Q: How can be identify/verify already programmed Actel device?

A: There are several possible options to get this done. Each option(action) is varying from

each other in method of comparing already programmed Actel device with loaded STAPL

file. There are the following appropriate mentioned actions in a STP file:

DEVICE_INFO: read and among other things display to log window also the checksum of

the programming environment programmed into the device. This value can be manually

compared by user with the value in the header of the STAPL file (can be viewed in

Information window). Caution: Value of the programmed device checksum isn't counting

from existing(maybe corrupted) device data content however this value is stored during

programming to special memory localization and is only reading!

VERIFY_DEVICE_INFO: similar options as previous with difference in automatic

comparison of programmed device checksum and STAPLE file checksum. The result of

comparison can be either success or error window message.

VERIFY: the safest but the slowest(~tens of seconds depends on device capacity against

~1 second in options 1 and 2) option for data compare programmed device content with

content of STAPLE file. Comparison selected family features(FPGA Array, targeted

FlashROM pages, security setting...) is executing bit by bit and verification process can be

early terminated if data mismatch occurs with writing error message to log window.

Q: Is it possible to program Actel device with two different STAPLE file in one program action

in PG4UW?

A: Yes, it is possible. PG4UW control program has built-in multi-project solution for

mentioned situation. As an example can be programming data content (first STAPL file)

together with security encryption key(second STAPL file).
