Hi...I got task to insert scan-chain in a design...initially I was getting D2,D8 violations...I resolved them by declaring clock which is present in design as "scan clock" and making some flops non-scanable bcoz RESET was going to their input logic via some combo logic...my senior told me that u should always make flops non-scan if reset is going that way.
Now after inserting DFT , I am getting post DRC S19...I studied it, it says "Nonscan cells must hold their state during the application of the load_unload procedure".
I dont know how to proceed now...if I again make them scanable then D8 violations will occur.
