[Amruth]

rising or falling time at o/p of a standered cell is called as Transition

i.e, load takes some time to charge or discharge right

i hope it will help you

Whenevera signal chages its value from '0' to '1' or '1' to '0' we call it as transition.

yup, when output signal changes, it goes a gradual rise/fall in analog domain..

如果没有读懂英文的话，芯片设计的软件很难用哟。:!:

u r transition in the synthesis level is depends on the wire load models . i hope u know wat is wire load model.

wire load model is a timing model it depends upon the fanout

Transition should be set based on the library being used
