All this is telling you is that there are some assertions (device checks) defined in your model files, and that they are all turned on. Depending on the value of "checklimitdest" (on the Simulation->Options->Analog form), you can control whether the violations get reported in the log file, in a separate file, or in the PSF results (can be both the log/external file and PSF). If saved to PSF, you can access them via Results->Violations Display, but also by looking in the results browser.
Precisely what the device checks are for is dependent upon the implementation in your models. Hopefully somebody has documented them...
