Debugging Of Large-scaled Data Processing Systems Like Supercomputers Is Becoming More Difficult. One Of The Causes Of The Trouble Is A Long Time For Reproducing VlSI's To Change Logic Design. An Automated On-chip Direct Wiring Modification System, Using Focused Ion Beam (FIB) And Laser CVD, Was Developed. It Reduced The Logic Change Period To One Day. The Debugging Time Of The Newest Mainframe Computer M880 Was Shortened By A Few Months.
