Electrothermal Simulation Example<br />

* Electrothermal simulation example - syntax 2 (external definition)<br />

.SUBCKT test a b<br />

ra a b 1k tc1 = 0.1<br />

.ENDS<br />

.tempnode subckt=test thnode=thn<br />

.option numdgt = 10<br />

v1 a 0 100<br />

x1 a b test<br />

r2 b 0 1k<br />

rthn x1.thn 0 10<br />

.op<br />

.extract dc i(v1)<br />

.extract dc TEMP(x1)<br />

.end<br />

The .TEMPNODE command specifies a thermal node thn in the subcircuit test. Its hierarchical<br />

name x1.thn is used to connect it to a thermal network. The thermal net here is a single resistor,<br />

rthn, it emulates how the power generated by devices attached to node thn is dissipated to the<br />

thermal ground 0. The syntax TEMP(x) is used to plot/extract the actual temperature value of an<br />

X instance or the temperature of a device.<br />
