The controlled source elements take an output function parameter. The output function takes the inputs, if any,
as parameters (which will be <tt>a</tt>, <tt>b</tt>, etc. for a voltage-controlled source, or <tt>i</tt> for a current-controlled source). You
can also specify <tt>t</tt> for
the current simulation time, <tt>timestep</tt> for the timestep, <tt>pi</tt> for &pi;, and <tt>e</tt> for <i>e</i> (unless there is an input <tt>e</tt>).
<p>
The function can use arithmetic like <tt>a+b</tt>, <tt>a*b</tt>, <tt>a^2/(b-1)</tt>, etc. It can also use functions like
<tt>sin(x)</tt>,
<tt>cos(x)</tt>,
<tt>abs(x)</tt>,
<tt>exp(x)</tt>,
<tt>log(x)</tt>,
<tt>sqrt(x)</tt>,
<tt>tan(x)</tt>,
<tt>floor(x)</tt>,
<tt>ceil(x)</tt>,
<tt>mod(x,y)</tt>,
<tt>max(x,y,...)</tt>,
and
<tt>min(x,y,...)</tt>.
</p><p>
It can also use conditional expressions like <tt>(a > 5) ? a+1 : b-2</tt>.
</p><p>
The <tt>tri(x)</tt> function is like <tt>sin(x)</tt>, but generates a triangle waveform.
</p><p>
The <tt>saw(x)</tt> function is like <tt>sin(x)</tt>, but generates a sawtooth waveform.
</p><p>
The <tt>step(x)</tt> function is 0 if <tt>x</tt> < 0, and 1 otherwise. (Equivalent to <tt>x >= 0</tt>).
The <tt>step(x,y)</tt> function is 1 if 0 < <tt>x</tt> < <tt>y</tt>, and 0 otherwise. (Equivalent to <tt>0 < x && x < y</tt>).
</p><p>
The <tt>clamp(x,lo,hi)</tt> function is equal to <tt>min(max(x, lo), hi)</tt>.
</p><p>
The <tt>select(x,a,b)</tt> function is equal to <tt>b</tt> if <tt>x</tt> is greater than zero, and <tt>a</tt> otherwise. So it's the same as <tt>(x > 0) ? b : a</tt>.
</p><p>
The <tt>pwl(x,x0,y0,x1,y1,x2,y2,...,xn,yn)</tt> function is short for piece-wise linear, and works as follows. If <tt>x < x0</tt>, then
the result is <tt>y0</tt>. If <tt>x0 < x < x1</tt>, then the result is a linear interpolation between <tt>y0</tt> and <tt>y1</tt>.
If <tt>x1 < x < x2</tt>, the result is a linear interpolation between <tt>y1</tt> and <tt>y2</tt>, etc. If <tt>x > xn</tt>, then the
result is <tt>yn</tt>. For example, in the simplest case, <tt>pwl(t,0,0,.1,5)</tt> is a waveform that starts at 0 at time 0 and then
ramps to 5 over 100ms, then stays at 5.
</p><p>
<tt>dadt</tt>, <tt>dbdt</tt>, etc. are equal to the time derivative of <tt>a</tt>, <tt>b</tt>, etc.
<tt>lasta</tt>, <tt>lastb</tt>, etc. are equal to the value of <tt>a</tt>, <tt>b</tt>, etc. in the previous timestep.
<tt>lastoutput</tt> is equal to value of the output function in the previous timestep.
