I came across a differential FF ( had data /datab and out/outb)which has a -ve setup time and +ve hold time. This has me throughly confused. Supposed the setup time is -10ps and hod time is 30ps ,and clock starts at 0s-does this mean in the time from the 0 to 30ps if there is a transition on the data , the FF fails?.. How would you distingusih between setup violation and a hold violation?
Moreover if the data transistion is from 0 to 1 or 1 to 0 how would this affect the setup/hold time?
Would appreciate if anyone throws light on this....?
