Abstract
An integrated circuit debugging system is provided for debugging the integrated circuits with bi-directional terminals is disclosed. The system includes clock unit for providing clocks, and address generating unit for generating address responsive to the provided clock. An I/O control memory is used to store pin status of an integrated circuit under test corresponding to each of the generated address; and a timing diagram memory is used to store fitting value of the integrated circuit. Moreover, the system includes an I/O manipulating unit for directing signal into and out of the integrated circuit according to the stored pin status of the I/O control memory, and for comparing the signal out of the integrated circuit under test and the fitting value from the timing diagram memory. Further, feedback control unit is configured to control the address generation of the address generating unit.
