The

The **rusage** command is used to obtain information about the
consumption of system resources and other statistics during the
* WRspice* session.

If any resource keywords are given, only those resources are printed. All resources are printed if the keywordrusage [all] [resource...]

The **stats** command is almost identical to **rusage**, and
accepts the same keywords. The difference is that **stats** given
without arguments will print all run statistics.

`accept`

This keyword prints the number of accepted time points from the last transient analysis.`cvchktime`

Print the time spent checking for convergence in the most recent dc or transient analysis (including operating point).`elapsed`

This keyword prints the total amount of time that has elapsed since the last call of the**rusage**or**stats**command with the`elapsed`keyword (explicit or implied with ```all`''), or to the program start time.`equations`

Print the number of nodes in the current circuit, including internally generated nodes. This includes the ground node so is one larger than the matrix size.`faults`

This keyword prints the number of page faults and context switches seen by the program thus far. See also*pagefaults*,*involcxswitch*, and*volcxswitch*for the values that occurred during the last anslysis.`fillin`

Print the number of fillins generated during matrix reordering and factoring. This is not available from KLU.`involcxswitch`

This provides the number of involuntary context switches seen during the last analysis. If multiple threads are being used, this is the total for all threads.`loadtime`

If given, print the time spent loading the matrix in the last simulation run. This includes the time spent in computation of device characteristics.`loadthrds`

Report the number of threads used for device evaluation and matrix loading during the most recent dc (including operating point) or transient analysis. This would be at most the value of the*loadthrds*option variable in effect during the analysis, but is the number of threads actually used.`loopthrds`

Report the number of threads in use for repetitive analysis in the most recent analysis run. This would be at most the value of the*loopthrds*option variable in effect during the analysis, but is the number of threads actually used.`lutime`

The`lutime`keyword will print the time spent in LU factorization of the matrix during the last simulation run.`matsize`

Print the size of the circuit matrix.`nonzero`

Print the number of nonzero matrix elements.`pagefaults`

Report the number of page faults seen during the most recent analysis.`rejected`

This keyword prints the number of rejected time points in the last transient analysis.`reordertime`

Print the time spent reordering the matrix for numerical stability in the most recent simulation.`solvetime`

This will print the time spent solving the matrix equations, after LU decomposition, in the last simulation run.`space`

This keyword will print the memory presently in use by.*WRspice*`time`

This keyword will print the time used by the last simulation run.`totaltime`

If this keyword is given, the total time used in the present session will be printed.`totiter`

This keyword prints the total number of Newton iterations used in the last analysis.`trancuriters`

This prints the number of Newton iterations used in the most recent transient analysis time point evaluation.`traniter`

The`traniter`keyword will print the number of iterations used in the last transient analysis. This does not include iterations used in the operating point calculation, unlike`totiter`which includes these iterations.`tranitercut`

The number if times that the most recent transient analysis had a time step cut by iteration count. If the*itl4*limit is reached when attempting convergence at a transient time point, the timestep is cut and convergence is reattempted.`tranlutime`

The time spent LU factoring the matrix in the most recent transient analysis, not including the dc operating point calculation.`tranouttime`

Print the time spent saving output in the most recent transient analysis.`tranpoints`

This keyword prints the number of internal time steps used in the last transient analysis.`transolvetime`

This keyword prints the matrix solution time required by the last transient analysis, not including the operating point calculation.`trantime`

This keyword will print the total time spent in transient analysis in the last transient analysis, not including the operating point calculation.`trantrapcut`

This is the number of times in the most recent transient analysis that a timestep was cut due to the trapcheck algorithm. This may occur when the*trapcheck*variable is set, which enables a test to detect numerical problems in trapezoidal integration.`trantstime`

Report the time spent computing the next timestep in the most recent transient analysis.`volcxswitch`

This provides the number of voluntary context switches seen during the last analysis. If multiple threads are being used, this is the total for all threads.
