st: estimate simultaneous equation model for panel data

["Bin Sun" <emailsunbin@gmail.com>]

Dear all,
Would you please give me some help to estimate simultaneous equation model for panel data and do the Hausman test for exogeneity? 
Does STATA have built-in routines? 
I also found the same question in last year's list archive, but could not get an answer.I really hope some routines have appeared.
Thank you very much
Bin
