Please suggest final project ideas for a layout course!!

[NightHawk_099]

I will be imparting a hands-on trainning course on physical design (layout) and Im looking for ideas on what should be final project be. I need something that is:

Relatively Small (Can be layed out in 2 or 3 days by an experienced designer)
Is very suceptible to layout variation (Shows how important layout is becoming in advanced technology nodes)
The cooler, the better (No counter, temperature controlers or the like)
Is Mixed signal

Since I have gotten great ideas from this forum, I thought I should ask...
Thanks in advance

i think make a differential opamp in comparator mode.put two inverters at output to make output buffered.
it will become a mixed signal as well as
it gives u feel of doing real analog layout
it utilizes all good concept of matching and inverters can be made using hierarchical flow.
