Step 2: Create a .svf File
The Quartus
®
II software generates .svf files for programming one or more devices.
When targeting multiple devices in the same MAX II and MAX V device families, the
Quartus II software automatically generates one .svf file to concurrently program the
devices. Therefore, the programming time for all of the devices approaches the
programming time for the largest CPLD device in the IEEE Std. 1149.1 JTAG chain.
Figure 2 shows the Create JAM, SVF, or ISC File dialog box in the File menu that you
can use to generate the .svf file.
Before creating the .svf file, open the Programmer in the Quartus II software and add
the Programmer Object File (.pof) for all the devices in the chain into the programmer.
Each .pof corresponds to each targeted device.
In the Create JAM, SVF, or ISC File dialog box, the value in the TCK frequency box
must match the frequency that TCK runs at during the test. If you enter a different
frequency from the frequency used in the test, your programming might fail or you
might experience an extended programming time.
You can select whether to perform a program operation or verify an operation and
optionally to verify or blank-check the device by turning on the Programming
options. Altera recommends generating .svf files that include verify vectors, which
ensure that programming failures are identified and a limited amount of additional
programming time is used. You can generate the necessary .svf files based on the
scan-chain topology of the board and the Altera devices to be programmed. After the
.svf file is generated, you can give the files to the test engineers for development.
If you program a device independently, generate an individual .svf file for each Altera
device in the chain. When you create the .svf file for a single device in the chain,
specify the .pof for the device and set the rest of the devices to <none> by selecting
Add Device in the Programmer. These devices are bypassed during programming.
Repeat this process until all your targeted devices have a .svf file.
