Major LHC upgrades planned around 2020 are expected to increase the delivered instantaneous luminosity above 10³⁴ cm^-2s^-1 while keeping the bunch spacing at 25 ns, or even increasing it. In order to cope with the higher pileup, the CMS collaboration is planning to build a completely new tracking system, which will probably implement also trigger capabilities. In order to identify the best possible design, a tool was developed (tkLayout) to generate layouts, make an estimate of the material budget and even provide an a priori estimate of the tracking performance. tkLayout can be used to optimize a given layout concept, or to compare the performance of different approaches. tkLayout is not speci?c to CMS, thus it can be used to design upgrades for other experiments. The technology of tkLayout is presented and results for several layout designs discussed.
