  In this paper, we present the design and the expected performance of the
classical Lyot coronagraph for the high contrast imaging modes of the
wide-field imager MICADO. MICADO is a near-IR camera for the Extremely Large
Telescope (ELT, previously E-ELT), with wide-field, spectroscopic and
coronagraphic capabilities. MICADO is one of the first-light instruments
selected by the ESO. Optimized to work with a multi-conjugate adaptive optics
corrections provided by the MOARY module, it will also come with a SCAO
correction with a high-level, on-axis correction, making use of the M4 adaptive
mirror of the telescope.
  After presenting the context of the high contrast imaging modes in MICADO, we
describe the selection process for the focal plane masks and Lyot stop. We will
also show results obtained in realistic conditions, taking into account AO
residuals, atmospheric refraction, noise sources and simulating observations in
angular differential imaging (ADI) mode. Based on SPHERE on-sky results, we
will discuss the achievable gain in contrast and angular separation provided by
MICADO over the current instruments on 10-m class telescopes, in particular for
imaging young giant planets at very short separations around nearby stars as
well as planets on wider orbits around more distant stars in young stellar
associations.
