Abstract
Future HEP experiments require detailed simulation and advanced reconstruction algorithms to explore the physics reach of their proposed machines and to design, optimise, and study the detector geometry and performance. To synergize the development of the CLIC and FCC software efforts, the CERN EP R&D roadmap proposes the creation of a “Turnkey Software Stack”, which is foreseen to provide all the necessary ingredients, from simulation to analysis, for future experiments; not only CLIC and FCC, but also for proposed Super-tau-charm factories, CEPC, and ILC. The software stack will facilitate writing specific software for experiments ensuring coherency and maximising the re-use of established packages to benefit from existing solutions and community developments, for example, ROOT, Geant4, DD4hep, Gaudi and podio. As a showcase for the software stack, the existing CLIC reconstruction software, written for iLCSoft, is being to be ported to Gaudi. In parallel, the back-end of the LCIO event data model can be replaced by an implementation in podio. These changes will enable the sharing of the algorithms with other users of the software stack. We will present the current status and plans of the turnkey software stack, with a focus of the adaptation of the CLIC reconstruction chain to Gaudi and podio, and detail the plans for future developments to generalise their applicability to FCC and beyond.

Summary
Experiments at future colliders require advanced software to simulate detector geometries and to reconstruct physics events in order to estimate and optimise the performance of the experiment and maximise the physics reach. The different communities for future experiments – CLIC [1], FCC [2], ILC [3], SCT [4], STC [5], Muon Collider [6] – came to the agreement that the development of a common software solution would benefit everyone [7]. In these proceedings we describe the proposal of the turnkey software stack, outline the requirements and foreseen ingredients, and showcase the evolution of the reconstruction for CLIC towards this common software solution
