The errors that you have attached below are not necessarily related to the
reason your simulation is failing. The QC reporting mechanism relies on
results generated during the course of a successful simulation, and the fact
that you are unable to a simulation is the reason for some of the nonsensical
numbers in the QC reporting results. Check the .sim file for information
on why the simulation won't run.<br>
