New component


 

hi, I want to make spesific electronic component.. my component contents codes.(for which etc... in matlab). can i make my component using codes. is there any property of ltspice..if answer is yes, how can i make ??

this is my component matlab codes. my ?nput is voltage and my output is current (I). I think my component has one input and one output. I want to create new block and my block must work as below. when i apply sine wave to input i must take current from my output. is there any code part in ltspice (using any language)

"Ron=1000;
Roff=160000;
x(1) = 0.5;
xDiff = 0;
time_step=0.0001;
t = (0:time_step:1);
voltage=sin(2*pi*t);
I = zeros(size(voltage));
for i=2:length(voltage),
? ? ? ? ?
? ?M(i-1)=(Ron.*x(i-1))+(Roff.*(1-x(i-1)));
? ? F=(1-((2.*x(i-1))-1)^20);
? ??
? ? ?I(i-1)=voltage(i-1)/M(i-1);
? ? ?dxdt=66000*I(i-1)*F;
? ? ?xDiff = dxdt*time_step;?
? ? ?x(i)=x(i-1)+xDiff;
end
?plot(voltage,I);"

LTspice does not link to external programs or code. But it has a capable
user-programmable component in the form of the BI behavioral element. It
is a current-output device. If you can write an expression for what you
want the current to be, using the rules listed in the Help file, you can
create a BI element that does it.

Take a look in the Help utility under LTspice > Circuit Elements > B.
Arbitrary Behavioral Voltage or Current Sources. The Help for Dot Commands
.FUNC and Dot Commands > .PARAM may also be useful.
