1.8.1 Enabling Early and Fast Thermal Simulation for 3D Multi-Die System Designs

Dear DATE community,

We, the DATE Sponsors Committee (DSC) and the DATE Executive Committee (DEC), are deeply shocked and saddened by the tragedy currently unfolding in Ukraine, and we would like to express our full solidarity with all the people and families affected by the war.

Our thoughts also go out to everyone in Ukraine and Russia, whether they are directly or indirectly affected by the events, and we extend our deep sympathy.

We condemn Russia’s military action in Ukraine, which violates international law. And we call on the different governments to take immediate action to protect everyone in that country, particularly including its civilian population and people affiliated with its universities.

Now more than ever, our DATE community must promote our societal values (justice, freedom, respect, community, and responsibility) and confront this situation collectively and peacefully to end this nonsense war.

DATE Sponsors and Executive Committees.

As design complexity increases with 3DICs and time-to-market becomes a critical component in the automotive, wearables and IoT segments, reducing design cycle time while maintaining accuracy of analysis has become all the more important. To address this, a system level co-design approach in step with multi-physics analysis is presented. To mitigate errors due to manual exchange of data between various engineering teams spread across chip, package and board with design and analysis adding further level of exchange, a design flow incorporating simplification at the layout level is shown. The flow enables various levels of simplified models to be used, wherein data transfer between the complex 3D structures in layout to the thermal analysis tool is automated. The efficacy of the model simplification is verified through a test case showing comparable results for the simplified and full models.
