GetConvergenceInfo Function

Returns a string array providing convergence information about the most recent run. Each element of the array is a list of values separated by semi-colons. The output may be pasted into a spreadsheet program that has been set up to interpret a semicolon as a column separator. The first element of the array lists the names for each column and therefore provides a heading. The following headings are currently in use:

type	Node or Device
name	Name of node or device that failed to converge count Number of times node/device failed to converge during run
time (first step)	Time of most recent occurrence of a 'first step' failure.
required tol	Required tolerance for most recent 'first step' failure
actual tol	Tolerance actually achieved for most recent 'first step' failure
absolute val	Absolute value for most recent 'first step' failure
time (cut back step)	Time of most recent occurrence of a 'cut back step' failure.
required tol	Required tolerance for most recent 'cut back step' failure
actual tol	Tolerance actually achieved for most recent 'cut back step' failure
absolute val	Absolute value for most recent 'cut back step' failure
final?	Node or device failed on the final step that caused the simulation to abort
top analysis	Main analysis mode (Tran, DC etc.)
current analysis	Current analysis. Either the same as 'top analysis' or Op
op mode	Method being used for operating point. (PTA, JI2, GMIN or SOURCE)

A first step failure is a failure that occurred at the first attempt at a time step after a previously successful step. If a time point fails, the time step is cut back and further iterations are made. Failures on steps that have been cut back are referred to in the above table as cut back steps . Quite often the nodes or devices that fail on a cut back step are quite different from the nodes or devices that fail on a first step. The root cause of a convergence failure will usually be at the nodes or devices that fail on a first step .
