Security
When CONFIG_SECURE is set to ON the on-chip security fuses will be set and no readback of the general con-
tents (SRAM or Flash) will be supported through the ispJTAG port. The ispJTAG DeviceID area (including the User-
code) and the device Status Register are readable and not considered securable. Default is OFF.
Usercode
Usercode is a user defined 32-bit register, sometimes called the UES (User Electronic Signature). The Usercode
can be thought of as a user “notepad”. The Usercode is supported as part of the IEEE 1149.1 definition.
Lattice incorporated the Usercode to store such design and manufacturing data as the manufacturer's ID, program-
ming date, programmer make, pattern code, checksum, PCB location, revision number, and product flow. The
intent is to assist users with the complex chore of record maintenance and product flow control. In practice, the
Usercode can be used for any of a number of ID functions. The Usercode can be easily edited using the User-
code/UES Editor in ispVM
Note that the Usercode is included in the file transmission checksum, but not the fuse checksum.
Configuring SRAM or Programming Flash
The final step in the design process is to load the JEDEC file created by ispLEVER or Diamond into the MachXO.
The JEDEC file can be used to configure the SRAM or program the Flash. Simply connect a Lattice download
cable to the ispJTAG connector that is wired to your MachXO and apply power to the FPGA. Then start ispVM and
follow these steps:
If you need to create an SVF (Serial Vector File), a file to allow programming from your ATE (Automated Test Equip-
ment), or a file to support VME (ispVM Embedded), simply perform steps 1, 2, and 3 above but click on SVF, ATE,
or VME instead of GO.
More information on ispVM and ispVM Embedded can be found by starting ispVM and clicking on Help. Here you
will find several tutorials as well as the help facility.
