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
<http://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).
The IspVM Virtual Machine
The IspVM Virtual Machine is a Virtual Machine that has been optimized specifically for
programming devices which are compatible with the IEEE 1149.1 Standard for Boundary Scan
Test. The IspVM EMBEDDED tool combines the power of Lattice's IspVM Virtual Machine
TM
with the industry-standard Serial Vector Format (SVF) language for Boundary Scan
programming and test.
The IspVM System software generates VME files supporting both ispJTAG and non-Lattice
JTAG files which are compliant to the IEEE 1149.1 standard and support SVF or IEEE 1532
formats. The VME file is a hex coded file that takes the chain information from the IspVM
System window. The devices can be programmed in ZIF socket of the programmer or in target
