This record is used to define an optional standard inductor decade. If present before the .CKT record (see below), the .STDL record will force the use of inductor values taken from a standard decade. Standard decades are defined by inductor manufacturers and indicate what values are available for a particular inductor series. For example, the ten percent standard inductor decade has 12 values between 1.0 and 10.0. The ten percent standard inductor decade could be defined to CCICAP with the following record:
.STDL 1.0 1.2 1.5 1.8 2.2 2.7 3.3 3.9 4.7 5.6 6.8 8.2
The values must be 
1.0 and < 10.0 and must be in increasing
order as in the example above.
If a .STDL record is processed before the .CKT record, any inductor values specified in the circuit will be changed to the closest standard decade value. For example, an inductor specified as:
L l23 nd1 nd2 8.3759e-3
will be changed to an inductor with a value of 8.2e-3 Henries. The new value, selected from the standard decade, will be shown on the circuit listing in the ASCII output file.
Standard inductor decades are easily added and removed from an analysis by the use of the .INC feature. For example, the following record would add a standard decade to an analysis:
.INC stdl.10
assuming that the file stdl.10 exists and consists of the .STDL record shown above. To remove the standard decade, the .INC record could be commented out:
*.INC stdl.10
Elements whose values are changed via an .ALTEL record are not forced to be from a specified standard decade. This allows for nonstandard inductor values for selected inductors during a subsequent analysis of the circuit.
