+ETH Zürich has [[https://github.com/pulp-platform/croc|Croc]] as an example used in classes. The project contains a processor and the flow scripts using Bender, Yosys, OpenROAD and KLayout.
+They manage the tools setup via [[https://github.com/iic-jku/IIC-OSIC-TOOLS/tree/main|IIC-OSIC-TOOLS]]. That is a collection of install scripts for various tools for a docker image. It is curated by [[https://www.jku.at/en/institute-for-integrated-circuits-and-quantum-computing/about-us/team/univ-prof-dr-harald-pretl/|Harald Pretl]] from the [[https://www.jku.at/en/institute-for-integrated-circuits-and-quantum-computing/|Institute for Integrated Circuits and Quantum Computing]] in Linz.
 ==== Install ====
 The [[https://github.com/The-OpenROAD-Project/OpenROAD|OpenROAD code is available on github]]. OpenROAD provides several install methods like docker, nix, bazel and cmake.
+OpenROAD is the tool for the backend part. OpenROAD provides [[https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts|OpenROAD flow scripts]] which can do the full flow from HDL to GDSII using additional tools like [[https://yosyshq.net/yosys/|YoSys]].
+To install all tools for the [[https://openroad-flow-scripts.readthedocs.io/en/latest/tutorials/FlowTutorial.html|OpenROAD flow tutorial]] i have made the [[https://github.com/fredowski/thavlsibuild|THA VLSI build]] script repository.
+The following parts are only for the OpenROAD tool.
+=== Download the OpenROAD git repository ===
+<code>
+git clone --recurse-submodules https://github.com/The-OpenROAD-Project/OpenROAD.git
+cd OpenROAD
+</code>
 === Install via bazel ===
-Bazel promises a reproducable build which I liked. I tried it on a virtual (via UTM) debian 13 (trixie) arm64 machine. The openroad binary is a gui application which relies on qt. It seems quite difficult to have system independent gui application. OpenROAD uses prebuild libraries, for example the xcd libraries which are from [[https://github.com/The-OpenROAD-Project/qt_bazel_prebuilts/tree/main/interface_libs|OpenROADS qt_bazel_prebuilts/interface_libs]]. There it turns out

Therefore they are x86_64 and do not work on the arm64 machine.
+== Install bazelisk ==
+See: https://github.com/bazelbuild/bazelisk/releases/tag/v1.28.1
+for the different systems. For debian linux on x86_64 machines do:
+<code>
+wget https://github.com/bazelbuild/bazelisk/releases/download/v1.28.1/bazelisk-amd64.deb
+sudo dpkg -i bazelisk-amd64.deb
+</code>
+== Build and Run openroad in cmdline mode ==
+The will build and run the openroad tool in cmdline mode.
+<code>
+bazelisk run //:openroad
+</code>
+== Build and run in gui mode ==
+<code>
+bazelisk run --//:platform=gui //:openroad -- -gui
+</code>
+== Run the regression test via bazel ==
+The following command will run all tests which are defined in the
+src folder. The three dots are real.
+<code>
+bazelisk test src/...
+</code>
+== Run one test from the regression ==
+<code>
+bazelisk test src/gpl/test:simple01-tcl_test
+</code>
+== Run the flowtests via bazel ==
+<code>
+bazelisk test //test:flow_tests --jobs=1
+bazelisk test //test:tinyRocket_nangate45-tcl_test
+bazelisk test //test:ibex_sky130hs-tcl_test

+=== Regression Test ===
+To be sure that the compiled tools are actually working as expected on possibly different platforms, a regression test is a good idea. The [[https://github.com/The-OpenROAD-Project/OpenROAD/blob/master/README.md|README.md]] mentions some tests. Run:
+<code>
+./test/regression flow
+ctest --test-dir build -j 8
