.table Line

General Form:
.table name [ac] x₀ v₀ x₁ v₁ ... x_N v_N

Examples:
.table tab1 0 .1 1n .2 2n .4 3n .2 4n .1 5n 0
.table xgain 0 0 1 1 1 1.5 4 2
.table acvals ac 0 1.0 0, 1e3 .98 .03, ...
.table zz (0 table xgain 4 2)
.table tab1 0 1 .2 .5 .4 table txx .8 .5e-2

The .table line defines a tabulation of data points which can be referenced from other lines in the SPICE file. The data are listed in sequence with respect to the ordinate x_N . The elements are separated by white space or commas, and may optionally be surrounded by parentheses. Generally, the table construct consists of many lines, using the `+' or backslash line continuation mechanism. When a table is referenced, the data value returned is interpolated from the values in the table.

The x_i in the .table line are values of the independent variable (i.e., the variable given as an argument to the referencing function). The v_i entries can be numbers, or a reference to another table in the form

table subtab_name

in which case that table will be referenced to resolve the data point.

If the ac keyword is given, the data numbers v_i are expected to be complex values, which are expressed as two values; the real value followed by the imaginary value. Any sub-tables referenced must also have the ac keyword given. The ac tables provide data for frequency-domain analysis. Without ac, all values are real, and the table is intended for use in dc or transient analysis.

A non-ac table is referenced through a tran-function (see 2.15.3). Tables with the ac keyword given are referenced through the ac keyword in dependent and independent sources (see 2.15 and 2.15.4).

Let x be the input variable associated with the device referencing a table. The table is evaluated as follows:

x < x0	val = v0(x0)
x0 < $\tt x$ < x1	val = v0($\tt x$) if v0 is a table val = interpolation of v0(x0) and v1(x1) if v0 is a number ...
x > xN	val = vN($\tt x$) if vN is a table val = vN if vN a number val = vN-1(xN) if vN is omitted

See the section A.3 for sample input files which illustrate the use of the .table line.
