EPI designs and manufactures advanced development and debug tools for embedded designs that use high-performance RISC microprocessors. It uses no target memory and requires no porting to the target system.
Tornado supports two debugging modes, system mode and task mode.
In system mode, the debugger sees the entire system as a single program to be debugged. This mode also can be used to test standalone executables, such as diagnostics, that do not run on VxWorks. A characteristic feature of system mode debugging is that when a breakpoint is reached, the processor halts and is put into debug mode. System mode is closest in concept to a hardware emulator, since debugging focuses on the state of the processor. Some degree of task awareness exists in this mode.
