(IMPORTANT!) ATTENTION: Contributors to and users of open-source (standalone) OpenROAD tools, please note the following. OpenROAD developers guarantee that each tool package (RePlAce, TritonSizer, TritonCTS, etc.) builds on a clean CentOS 6 virtual machine. Each tool owner will ensure that packages come with their own required .so (shared library) files under their own release, and/or instructions for prerequisites as, e.g., bash scripts to “yum install”. Questions/comments can be sent to abk-openroad@eng.ucsd.edu or individual OpenROAD tool developers.
