Did you check System Architect 9.x from popkin software?
You can ask a demo to them, I'm almost sure I saw that in there.

Subject: Academic ERDs vs. Professional ERDs
I'm taking academic database classes and last semester we covered academic
ERDs. The material in the book discussed 'entity sets' and relationship
sets. The relations between them seemed very similiar to relations in a
class diagram.
However, I when I look into Erwin and Designer the ERDs there seem to be
closer to table models. Does anyone use the academic type of ERDs
professionally?
