In summary, Vishay’s PTC and RTD models are the ideal companions for any engineer designing a circuit board for circuit protection or temperature control with most EDAs. It does not matter if the programming language is SPICE or VHDL-AMS; the result will be the same. It is up to engineers to use the software of their choice, knowing now that Vishay can perform the required adaptations to make integration seamless. Simulation of an application may not be sufficient to fully advance the system, but it will help the designer to develop their intuition and visualize what the physical PTC or RTD components are capable of.
