QUARTUS II INTERNAL ERROR

Does this fatal error occur when you try to open the Quartus software or when you attempt to compile a design using Quartus?

If the error is due to design compilation, kindly share your design by archiving the project (Project > Archive Project) so that I can duplicate the issue.

The fatal error could also be a result of issues with the PC environment setup.

There are a few things that you can troubleshoot:

1. Try restarting Quartus and your computer. This can help clear any temporary issues that may be causing the error.

2. Check your system resources, including memory, CPU usage, and disk space. Make sure you have enough available resources to run Quartus.

3. Try disabling any antivirus or firewall software temporarily, as they may be interfering with Quartus.

4. Run Quartus as administrator.

5. Install currprocess https://www.nirsoft.net/utils/cprocess.html and disable all the software running behind there

6. If possible, try to run in another machine to see whether the error is machine related.
