You can ignore this. You can ignore most complaints from drc2: its  
model of reality is that you are designing pure logic circuits using  
a single logic family.

To the developers: why bludgeon newbies with the "need" to use a tool  
that requires deep understanding of its limitations to be at all  
useful? It's a tool for experts: its messages must be treated with  
enormous skepticism.

When in doubt, use "pas".

Nope. You don't need pintype at all, unless you want to suppress  
drc2's whining.
