Re: DFT question. 1. the number of scan chains also depends on chip area. because more IO ports are required for more scan chains. chip area gets increased (small increase) even if we share the scan pins with the signal ports. but use of more scan chains reduces testing time very much.
WebIn a bottom-up flow, DFT engineers typically allocate a fixed number of scan channels for each core, usually the same number for each core. This is the easiest approach, but it can end up wasting bandwidth because the different cores that are grouped together for testing might have different scan chain lengths and pattern counts.
