84 The interface between the simulator control package (SCP) and the
85 simulator consists of the following routines and data structures
86
87 sim_name simulator name string
88 sim_devices[] array of pointers to simulated devices
89 sim_PC pointer to saved PC register descriptor
90 sim_interval simulator interval to next event
91 sim_stop_messages[] array of pointers to stop messages
92 sim_instr() instruction execution routine
93 sim_load() binary loader routine
94 sim_emax maximum number of words in an instruction
95
96 In addition, the simulator must supply routines to print and parse
97 architecture specific formats
98
99 print_sym print symbolic output
100 parse_sym parse symbolic input
