Is REGCNT.opt.db in the memory ?

If u know the library Name, please use the foll. command. swap_cell U3 [get_lib_cell $libname:REGCNT] If u dont know the lib name, the get the lib using list_libraries command and then replace $libname with that library.

What I infer from your command is the lib name in db is REGCNT and you need to know the library cell name to provide with the command.
