makefile: add preview_macro_placement target
for manual placement io pin placement can be skipped, which simplifies macro placement debugging as io pin placement can fail if the floorplan is completely wrong. for automatic placement, the normal flow is run and then the gui shows the 2_4_floorplan_macro.odb. make clean_floorplan preview_macro_placement Signed-off-by: Øyvind Harboe <[email protected]>
