The high luminosity operation of the LHC will require an upgrade of the CMS silicon tracker, possibly implementing trigger capabilities. In order to evaluate the possible options and geometries, a standalone software package has been developed (tkLayout) to generate detector layouts, evaluate the effect of inactive material and provide an a priori estimate of the tracking performance. The package can be used to compare the performance of different options, and then to optimize the chosen
