13. The input support method according to claim 9 , wherein the code analyzing step counts the number of member access operators included in the input character string created by the code editing step, acquires the input character string as the hierarchical character string of a first hierarchy if the counted number of member access operators is zero, acquires the character string of the input character strings before the member access operator as the hierarchical character string of a first hierarchy, and the character string subsequent to the member access operator as the hierarchical character string of a second hierarchy if the counted number of member access operators is 1, and acquires the character string before a first member access operator as the hierarchical character string of a first hierarchy, the character string before a second member access operator as the hierarchical character string of a second hierarchy, and the character string subsequent to the second member access operator as the hierarchical character string of a third hierarchy if the counted number of member access operators is 2.
14. The input support method according to claim 13 , wherein the hierarchical database includes a first hierarchy having a module name as a search key, a second hierarchy forming a lower hierarchy of the module name and having a register name as the search key, and a third hierarchy forming a lower hierarchy of the register name and having a bit name as the search key, and has information on the register manual of the data processing LSI as the guide information.
