Below is a file which illustrates some features exclusive to * WRspice*
for specifying the output of sources.

WRspice function and table demo * * WRspice allows arbitrary functional dependence in sources. This * file demonstrates some of the capability. * * v1 is numerically equal to the exponentiation of * 2 times the sine. "x" is replaced by the time variable. v1 1 0 exp(2*sin(6.28e9*x)) r1 1 0 1 * * v2 obtains values from table t1 v2 2 0 table(t1, time) r2 2 0 1 .table t1 0 0 100p .1 500p 0 750p .2 1000p 0 * * v3 is a 0-1 ramp v3 3 0 pwl(0 0 1n 1) r3 3 0 1 * * e1 illustrates use of sub-tables. x is the voltage from v3 e1 4 0 3 0 table(t2, x) * below is an alternative equivalent form for e1 *e1 4 0 t2(v(3)) r4 4 0 1 .table t2 0 table t3 .5 table t4 .75 .75 1 0 .table t3 0 0 .25 1 .5 0 .table t4 0 0 .5 0 .625 1 .75 .75, x) * * e2 produces the same output as e1, but uses a PWL statement. * when the controlling nodes are given, pwl uses the control source, * and not time when used in e,f,g,h sources e2 5 0 3 0 pwl(0 0 .25 1 .5 0 .625 1 .75 .75 1 0) r5 5 0 1 * .tran 1p 1n * type "run", then "plot v(1) v(2) v(3) v(4)" .end
