Model of the Month

Modeling a BJT-based temperature sensor circuit

Using the new 'npn' and 'pnp' primitives, you can model a circuit that produces a voltage or current as a function of temperature.

Tip of the Month

Enabling UVM in XMODEL simulations

Check out the new '--uvm' and '--uvm-option' options that can enable UVM and specify UVM-related options independent of the host simulator.

Primitive of the Month

npn

This primitive models a bipolar junction transistor with temperature-dependent characteristics.
