Hi,

Can anyone please explain in detail how the limit is set for clock tran and data tran?

I know it is based on some percentage (% ) of clock_period.
Like :
clock_tran limit --> x% of clock period
data_tran limit --> y% of clock period

But, I just want to know how they come up with that particular percentage(%).

Thanks in advance.
 

clock_tran limit 1/6 clock period
data_tran limit 1/3 clock period

at high or low pulse, assume 1/3 is rise tran, 1/3 is fall tran, then 1/3 is available?
above is my guess...
