The Owls will take on either Middlesbrough or Brighton & Hove Albion.
The Owls secured sixth place in the table this season, a fine end to what has been an impressive campaign for them.
That finish means they will play whomever finishes third in the table, with that position still yet to be decided as Middlesbrough and Brighton & Hove Albion clash to secure second place.
Either side will prove stern competition for Carvalhal’s side, but he insists that his team actually has an advantage over any potential competition.
“I think we have something that is in our favour in the last period of the competition,” he told the club’s official website. “We feel strong, no players are over training, some of the players who have played a lot of games we rest them, we manage all the squad and we feel strong.
“When I train with my team, I am not feeling we are near the end of the season. I feel they are strong like at the beginning and we saw that in the last game.”
Arguably Wednesday head into the play-offs as the outsiders given the stature of the other teams set to compete in them.
Indeed, as outsiders the pressure is very much on the other teams, which could be an important factor in the season’s showcase finale.
Wednesday are not to be underestimated though, having steadily improved this season after a slow start under the Portuguese boss.
They are in good form heading into it, too, as they stretched their unbeaten run to five games with a 3-0 win over Cardiff City at the weekend.
