Deployment Tool: Why are the fields between '65' and '5F' different when having SVF file and generates .vme file twice?

The 0x65 is the FILE_CRC command (used for CRC-protected to prevent corrupted or modified VME file). The FILE_CRC should be followed by 2 bytes of the CRC value which includes the sum CRC of all the bytes in the rest of the file. Eventhough the data are exactly the same; the difference of the…

FAQ

MachXO2: How to update the Configuration Flash of the MachXO2 in transparent mode using the svf file generated by Diamond Deployment Tool for the operation XFLASH Erase, Program, Verify?

The XFLASH Erase, Program, Verify instruction does not issue a refresh command. To update the Configuration Flash, use the XFLASH Erase, Program, Verify, Refresh operation, or power cycle the device.

FAQ

ispLEVER / ispVM System: Why does it take 4 minutes to program the XP2 FPGA device with the svf file generated by ispVM System software?

The official SVF standard does not support the looping and polling commands necessary to do a faster erase. In order to remain compatible with third party tools, we must use the worst case delay.Our SVF interpreter supports looping and status polling, so the SVF file can be modified by hand…

FAQ

Model 300 Programmer: What is the procedure to program a generic JTAG device using SVF Files and Model 300 Programmer?

The Model 300 Programmer can program any generic JTAG device, provided user have the correct SVF file for it. User can program any JTAG device that has a SVF file by selecting the correct adapter footprint and voltage in the Model 300 Programmer main window. To Program a JTAG-SVF…

FAQ

Lattice Diamond: What are some suggestions to improve SVF programming with ICT programmer similar with the Diamond programmer? 

In order to support the typical erase and programming delays, the programming algorithm must be able to read the status from the device and loop until the device has completed the erase or programming action. The SVF (Serial Vector Files) standard does not support looping. Thus, we must use the…

FAQ

Diamond: Why does the boundary scan device give LOOP 100 syntax error with an SVF file?

Some boundary scan devices do not support the LOOP command, which is why it's giving the syntax error. This LOOP command is a Lattice-specific SVF command. It's not defined in the Serial Vector Format Specification. The advantage of the LOOP command is that it takes much less time since user can…

Deployment Tool: Why does generated Rev D version of SVF (tester) in Deployment tool takes a long time to program on a device?

Description:The Rev D option will generate an SVF file that complies with revision D of the SVF standard. The SVF file standard does not support looping / status polling. In order to achieve fast erase and programming times for our Flash devices, the tool uses a status polling…
