.OPTIONS RSHUNT =100Meg The Rshunt option places a resistor every node in the circuit to ground
.OPTIONS RAMPTIME =10ns Ramptime causes all independent sources ramped up from zero initial values at beginn
.OPTIONS ALTINIT =10 Setting Altinit to 1 causesmore lenient algorithm used when UIC
.OPTIONS METHOD =gear default is "trapezoidal" (or just "trap").
.OPTIONS RELTOL =.01 sets accuracy, reset to default value of .001 after things working
.OPTIONS ABSTOL =1n sets accuracy, use 1u in amp applications default Abstol=1pA
.OPTIONS VNTOL =1m sets accuracy, default Vntol=1µV.
.OPTIONS TRTOL =x Sets transient error tolerance. default 7.0. an estimate of overestimates truncation error.
.OPTIONS ITL1 =400 dc iteration limit. default is 100.
.OPTIONS ITL2 =100 dc transfer curve iteration limit. default 50.
.OPTIONS ITL3 =x lower transient analysis iteration limit. default 4. (Note: not implemented in Spice3).
.OPTIONS ITL4 =500 transient analysis timepoint iteration limit. default is 10.
.OPTIONS ITL5 =x transient analysis total iteration limit. default 5000. Set ITL5=0 to omit test.not in Spice3.
.OPTIONS PIVREL =x Resets relative ratio between largest column entry and an acceptable pivot value. default 1.0e-3.
.OPTIONS PIVTOL =x Sets absolute minimum value for matrix entry to be accepted as pivot. default 1.0e-13.

.OPTIONS TEMP =x Sets operating temperature of the circuit. default s 27 deg C (300 deg K).
.OPTIONS TNOM =x Sets the nominal temperature at which device parameters
Add UIC (Use Initial Conditions) to the .TRAN line. Example: .TRAN .1N 100N UIC
Add .NODESET values Example: .NODESET V(6)=0
Add RC snubbers around diodes.
Add Capacitance for all semiconductor junctions
Add rise/fall times of the sources.
nodesets "filename" //Create a file of .nodeset statements
.NODESET: Specify Initial Node Voltage Guesses
.NODESET V(12)=4.5 V(4)=2.23
.NODESET V(6)=0 Add .NODESET values for top level circuit nodes (not subcircuit nodes)
.IC: Set Initial Conditions
uic on tran statement stops tran from doing op
starts with everything at zero unless specified with .ic statements.
safer to use a .IC statement and not specify UIC on the tran statement.
