DFT checks at RTL level

[sakshi gupta]

I just want to know , what kind of checks related to DFT we can check in RTL ?


Thanks

Basically, you can check clocks & resets controlability using tools like Cadence's HAL.
Also there are:
- combinational loops
- latches presence (if you are going to use multiplexed flip-flop scan style)
- resetless flip-flops

if you have spyglass tool, it will tell you some rule for DFT check in different level!

Controlability of clocks and reset can be checked
