General Form:

option [option=val] [option=val] ...

Set any of the simulator variables as listed in Chapt. 15.1. See this chapter also for more information on the available options. The option command without any argument lists the actual options set in the simulator (to be verified). Multiple options may be set in a single line.

The following example demonstrates a control section, which may be added to your circuit file to test the influence of variable trtol on the number of iterations and on the simulation time.

Command sequence for testing option trtol:

.control
set noinit

option trtol=1
echo 
echo trtol=1 
run
rusage traniter trantime
reset
option trtol=3
echo
echo trtol=3 
run
rusage traniter trantime
reset
option trtol=5
echo
echo trtol=5 
run
rusage traniter trantime
reset
option trtol=7
echo
echo trtol=7
run
rusage traniter trantime
plot tran1.v(out25) tran1.v(out50) v(out25)  v(out50)
