Voltus – Celsius Static Electrical Thermal Analysis

To run chip or IC thermal simulation, you can use the Celsius Thermal Solver in conjunction with the Voltus IC Power Integrity solution to do electrical and thermal analysis. Below flow shows flow for static (steady-state) electrical-thermal co-simulations for solid objects with layered structures or ICs.

To use the Voltus-Celsius thermal analysis flow, you can do the following:

1. Generate Voltus ‘Thermal Model’ to be consumed by Celsius.
2. Generate Celsius ‘Thermal Map’ to be consumed by Voltus.
3. Analyze ‘Power and EM/IR’ using Voltus applying Celsius thermal map.

The following flow diagram shows the information exchange between Voltus (Chip Power Sign-off tool) and Celsius Thermal Solver:

You can use this RAK to understand about the flow more in detail.
