Hi ,
In my design i have 4 clocks . I have some doubts regarding this with respect to DFT
1.How to decide scan clock out of 4 clocks
2.I have read somewhere that only one clock needs to be active , Why it is so,
3.Suppose if there is F1 which is clk1 and goes to combinational path and captures on F2 flop which is clk2.Since one clocks active at a time clk1 is active and clk2 is not .How are we going to test the combinational path since we are not capturing this data.
4.W.r.t STA , whether the above combinational path is a valid path to generate SDF? If so why.
Thanks in advance
