If you change the output file do not change the output file extension .max . Then click Apply ECO. Layout Plus will display the dialog shown in figure 2 after you apply ECO. In case of footprint linking error missing footprints on some components you will need to Univerisity of Maryland Baltimore County UMBC 1 CMPE 310 Fall 2006 Layout Plus Tutorial Ekarat Laohavaleeson give the footprints to all missing components to complete AutoECO. As explained in Capture CIS tutorial it is better to specify footprints to all .
