Usage

Exact usage may be simulator dependent. For example, whether the local temperature rise node for self-heating is made available or not, and whether the initial instance key-letter “r” is required.)

r<instanceName>  (<n1>  <nc>  <n2> [dt])  <modelName>  <instanceParameters>

.model  <modelName>  r3 <modelParameters>

The dt node is the rise above the local temperature caused by the thermal power dissipated by the device being modeled.
