Options in PSPICE

.OPTIONS (Options)
P Spice allows various options to control and to limit parameters for the various analysis. The general form is
.OPTIONS [ <(options)name>] [ <(options)name>=]
the options can be listed in any order. There are two types of options
1. With out values (used as flags of various kinds, and only option name is mentioned
2. With values (used to specify certain optional parameters, name and their values) as given below.

Option(with out values) Effects
LIST Causes summary of all circuit elements (or devices) tobe output
NOPAGE Suppresses paging and printing of a banner for each major section
NODE Causes out put of net list
Option (with values) Effects Unit Default

TNOM Default Temperature Degrees°C 27
ITL1 DC and Bias Point “blind” Iteration limit 40
ITL2 DC and Bias Point “educated guess” Iteration limit 20
ITL4 Iteration limit at any point in Transient analysis 10
ITL5 Total Iteration limit for all points in Transient analysis 5000
(ITL5=0 means ITL5=infinite)
RELTOL Relative Accuracy of voltages and currents 0.001
TRTOL Transient Analysis accuracy adjustment 7.0
ABSTOL Best Accuracy of currents Amps 1pA
CHGTOL Best Accuracy of charges coulomb 0.01Pc
VNTOL Best Accuracy of voltages volt 1uV
GMIN Minimum conductance used for any branch Ohm-1 1E-12
