The computer has done the simulation before, Modelsim can be perfect to call, but recently inexplicably there is a flashback problem, not through the Quartus or Ise call, when used alone will also flash back.
Occasionally, you can catch an error message. As shown in the following:
But the egg, there is no solution on the Internet, the most is the proposed re-installation system. Fortunately, colleagues have a great God, lest I delay time, at the same time found the root of the problem.
If someone is like me, can be called before, a sudden flash back, you can try my method.
1. Run cmd to bring up the command window. Run Command msconfig
The following window appears
2, select the startup bar, see the computer's Startup items have those, which is system-level disabled ~
When only a few harmless drivers are left, the Modelsim can be called out. After the adoption of the elimination method, a start-up program opened, the trial out of the Iqiyi art player caused the Modelsim can not start.
Hopefully this approach will also help other small partners.
