Set algebraic loop trace level


atrace level
at level



Trace level (0 = none, 4 = everything).


The atrace command sets the algebraic loop trace level for a simulation.


Displays for Each Algebraic Loop

atrace 0

No information

atrace 1

The loop variable solution, the number of iterations required to solve the loop, and the estimated solution error

atrace 2

Same as level 1

atrace 3

Level 2 plus Jacobian matrix used to solve loop

atrace 4

Level 3 plus intermediate solutions of the loop variable
