Debugging and cosimulation method for wide band switch firmware

An RS232C driver inside target firmware controls an RS232C interface. An OS debugger steals an input to and an output from another function block that is the actual target firmware, and exchanges that input and output with the RS232C driver 1005. This configuration makes it possible to easily connec...

Summary:An RS232C driver inside target firmware controls an RS232C interface. An OS debugger steals an input to and an output from another function block that is the actual target firmware, and exchanges that input and output with the RS232C driver 1005. This configuration makes it possible to easily connect a device that executes the target firmware to, for example, a personal computer, using a general purpose RS232C interface, and makes it possible to easily obtain debugging operation using the PC side debugger.
