Intro2Spanish.com: Spanish Verb Conjugation: Indicative: Conditional Perfect Tense

Perfect tenses use a form of "to have" along with the past participle of the verb or action stated. The participle form in English is the "---ed" form of a verb.

An English Verb Conjugated in the Past Perfect Tense
I would have slept	we would have slept
you would have slept	y'all would have slept
he, she, it would have slept	they would have slept

Note that the only change in these tenses is what you do with the verb to have. The same thing will be true in Spanish.

In Spanish, you use the verb haber (to be) along with the -ado or -ido form of a verb.

AR verbs:	-*ado*
ER & IR verbs:	-ido
