3D-ICE stands for 3D Interlayer Cooling Emulator. It is a Linux-based Thermal Emulator Library written in C, which can perform transient thermal analyses of vertically stacked 3D integrated circuits with inter-tier Microchannel Liquid Cooling. The latest version, namely 3D-ICE 3.1, supports fully customized non-uniform thermal modeling and different heat sink models. If you want to enable the SystemC wrapper, set the environment variable SYSTEMC=yes.
