Abstract
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.
Claims12
A wide band switch debugging device for performing debugging of a device that executes target firmware in a system, wherein the device that executes target firmware comprising:
- a general purpose interface driver module controls inputs to and outputs from a general purpose interface;
- and
- a debugger module captures inputs to and outputs from the target firmware for debug processing and switches said inputs and outputs with said general purpose interface driver module.
A wide band switch cosimulation device for performing debugging or cosimulation of a device that executes target firmware in a system, wherein the device that executes a simulation program for the target firmware or a simulation program for a hardware comprising:
- a general purpose interface driver module controls inputs to and outputs from a general purpose interface;
- and
- a connector module captures simulation programs for said target firmware or inputs and outputs of simulation programs for the hardware, and inputs them to or outputs them from a socket that is established between itself and another device or terminal that executes cosimulation, and additionally switches the data communicated through said socket with said general purpose interface driver module.
