Initial fix for Bug 710 -

"The log file appears blank when a VDMOS element is added".
The problen was caused by a crash during sensitivity analysis
caused by selecting parameters for wariation based on their
values.  That is not repeatable between passes.  The fix is to
remove that code, but it causes many more parameters to be used.
