.DATA Parameter Sweeps Examples
.DATA Parameter Sweeps Examples
The .DATA command simultaneously defines a set of parameters. For example:
.TRAN 1n 10n SWEEP DATA=datatran
.DATA datatran p1 p2 p3
+ 1.0 3.0 4.0
+ 2.0 5.0 7.0
.ENDDATA
Here follow some examples of specifying multiple external files to be processed either
sequentially or in parallel:
.data example1 MERGE
+ file=data1.inc col1=3 col2=2
+ file=data2.inc colA=1 colB=3
+ out=example1.inc
.enddata
After the first file name, the names of the columns to be created and the index where the data
comes from are specified. The resulting .DATA is created using the merge of the two files:
1 2 3
4 5 6
7 8 9
10 20 30
40 50 60
70 80 90
The specification col1=3 col2=2 and colA=1 colB=3 literally means: the first column is named
col1 and its values come from the third column of merged files; the second column is named
col2 and its values come from the second column of merged files. The resulting .DATA will be:
.DATA example1
+ col1 col2 colA colB
+ 3 2 1 3
+ 6 5 4 6
+ 9 8 7 9
+ 30 20 10 30
+ 60 50 40 60
+ 90 80 70 90
.enddata
The following example shows the LAMINATED specification for processing in parallel:
.data example2 LAM
+ file=data1.inc col1=3 col2=2
+ file=data2.inc colA=1 colB=3
+ out=example2.inc
.enddata
