Temperature-Aware Circuit Simulation for RFIC and MMIC Design
As higher power devices are integrated into smaller
packages, thermal issues cause performance degradation,
reliability problems, and even failures. Modeling
thermal effects can be challenging for IC designers. Existing
thermal solvers are not well integrated into IC design tools,
requiring manual and error-prone data transfer between the
layout environment, thermal solver and circuit simulators.
The Advanced Design System (ADS) Electro-Thermal
Simulator provides a full 3-D thermal solver that is tightly
integrated with the ADS layout environment and circuit
simulators. Simply add the Electro-Thermal controller to
the ADS schematic, start a circuit simulation and the
integrated thermal solver will run in the background. No
more manual export of IC layouts to stand-alone thermal
solvers; no more manual import of temperature data into
the circuit simulators.
Simulation Flow
The following steps illustrate the use of the ADS
Electro-Thermal Simulator.
1. An IC design is created in ADS with schematic and
layout views.
2. A simulation test bench is created by placing controllers
for one or more of the ADS circuit simulators in an ADS
schematic.
3. An Electro-Thermal controller is added to the schematic,
and settings for the thermal solver are adjusted
(Figures 1a and 1b).
4. A simulation is initiated, which launches both the circuit
simulator and thermal solver.
5. The circuit simulator computes initial power dissipation
values for each device in the circuit, and provides this to
the thermal solver.
6. The thermal solver computes initial temperature values
for each device and provides this back to the circuit
simulator.
7. The circuit simulator and thermal solver iterate until the
power dissipation and temperature values converge to a
inal solution.

solver together with the circuit simulator.
