When compiling Database using ncsim, two steps, ncvlog & ncelab.
There isn't syntex error and hierarchy connection error, but during elaboration, the program will be terminated by some unknow reason,
Ncsim only printed "Internal error".
what's the reason?
I know,internal error is the badest information for user,
you can contact to AE.
what can you do by yourself?
1) check your compile/elabration flow, to see if some constaint is not right.
2) if design problem,and remove some design ,try differenct flow.
3) if remove something ,design can compile ok.then found what is not compatible with ncverilog.
4) doest work.my god.wipe your perspiration.......................Kaddish
