This record is used to define an optional standard resistor decade. If present before the .CKT record (see below), the .STDR record will force the use of resistor values taken from a standard decade. Standard decades are defined by resistor manufacturers and indicate what values are available for a particular resistor series. For example, the one percent standard resistor decade has 96 values between 1.0 and 10.0. The one percent standard decade could be defined to CCICAP with the following multiple line record:
.STDR 1.00 1.02 1.05 1.07 1.10 1.13 1.15 1.18 1.21 1.24 1.27 1.30 \
1.33 1.37 1.40 1.43 1.47 1.50 1.54 1.58 1.62 1.65 1.69 1.74 \
1.78 1.82 1.87 1.91 1.96 2.00 2.05 2.10 2.15 2.21 2.26 2.32 \
2.37 2.43 2.49 2.55 2.61 2.67 2.74 2.80 2.87 2.94 3.01 3.09 \
3.16 3.24 3.32 3.40 3.48 3.57 3.65 3.74 3.83 3.92 4.02 4.12 \
4.22 4.32 4.42 4.53 4.64 4.75 4.87 4.99 5.11 5.23 5.36 5.49 \
5.62 5.76 5.90 6.04 6.19 6.34 6.49 6.65 6.81 6.98 7.15 7.32 \
7.50 7.68 7.87 8.06 8.25 8.45 8.66 8.87 9.09 9.31 9.53 9.76
The values must be 
1.0 and < 10.0 and must be in increasing
order as in the example above.
If a .STDR record is processed before the .CKT record, any resistor values specified in the circuit will be changed to the closest standard decade value. For example, a resistor specified as:
R r23 nd1 nd2 3.50843e3
will be changed to a resistor with value 3.48e3 ohms. The new value, selected from the standard decade, will be shown on the circuit listing in the ASCII output file.
Standard resistor 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 stdr.1
assuming that the file stdr.1 exists and consists of the .STDR record shown above. To remove the standard decade, the .INC record could be commented out:
*.INC stdr.1
To remove the effect of the STDR record for selected components, see the description of the .STD record.
There are two ways to specify resistor values that are not modified by a specified standard decade. A resistor can be specified as an equivalent conductance using a G type element (see .CKT section). The values of G elements are not changed by the presence of a standard decade. Additionally, elements whose values are changed via an .ALTEL record are not forced to be from a specified standard decade.
