HOLD path error for IGNORED TIMIING (TIG) parameter

[syedshan]

Hello ever one,

please note first that I am using Xilinx ISE for the following.

I cannot understand why do I have hold path violation at the path I have already ignored using TIG parameter.
Previously I was having setup path error, hence I put the TIG parameter so that I might have the error reduced and then I can check if my things are working right or not? but unfortunately I could not do so i.e. now I am getting HOLD path error....

cannot understand why????

any idea.

Are you sure the TIG actually is in effect? Those pesky constraints have way of letting you think you have applied them, but in actual fact they do as they please. I'd double check that the constraints are actually applied. Notably, make sure you apply the constraints to the flip-flops (registers), NOT some random wires aka signals. Been there, done that, t-shirts.
