Honored ContributorI have build my proyect in bigger device, EPM2210, and I have a new different problem. The total logic elements of EPM2210 is 2210, and for my proyect I need 2042 (92% of EPM2210), however the result of the compiltaion in a error.

error: quartus ii full compilation was unsuccessful. 4 errors, 34 warnings I dont know what happened, because the EPM2210 have more nº of total logic elements than my requeriments. Some suggestion to solve this? Regards Javi
