Glad you worked that all out, Curt.  Do you have the RTL description for 
any of those, or even a netlist?  In theory, a good LVS tool and lots of 
patience could infer the netlist from the layout.  In practice, it may be 
extremely difficult to back out anything usable (I work in the field, so 
this is not idle speculation).
