The Quartus II design software application is recommended to open the file. It was released by Altera.
How to open SOF file?
An often recurring problem with Quartus II SRAM Object is that SOF is not associated with the correct program file. Thus, when you open SOF, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the SOF file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Quartus II design software
The first step is to check if the computer has the Quartus II design software program installed. To do this, enter the name Quartus II design software into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support SOF files.
Programs to open SOF file
Remember to download programs supporting SOF files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Quartus II design software with SOF files
If the application is or has been freshly installed, but the SOF file still does not use the Quartus II design software program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the Quartus II design software application as the default for handling the SOF file.
Step 3. Update Quartus II design software to the latest version
The fault may also lie with the Quartus II design software program, it is possible that Quartus II SRAM Object requires a newer version of the program. This can be done using the application (if it provides such options) or from the Altera website and install the latest version.
Step 4. Check for the following problems with the SOF file
If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:
The affected file may be 0 KB or smaller than expected. Usually this applies to SOF files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file SOF or the program directory. However, remember that not every infected SOF file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the SOF file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged SOF files. You can restore the file from a backup or use Altera help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted SOF files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the SOF file to another location.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the SOF file for a certain period of time. If this does not work either, restart the device.
