How much should be the input rise time of the start/stop pulse to a TDC? What determines it?

ya, for IC's i can see the datasheets. But I wanted to design a TDC of my own, say a simple vernier delay line TDC. Based on what should I fix the limit of my input rise timeHi,
I don't understand your question .... because we don't know which IC you use nor do we know your application requirements.
General answer:
If I wanted to know this, I'd read it's datasheet.

yes, how much should it be fast, timing uncertainity i get it.At least fast enough to allow clear edge detection, preferably fast enough not to introduce additional timing uncertainty.
What are the parameters? Time range, resolution?I wanted to design a TDC of my own
ya, why do you expect 1ns rise time? what if rise time is poorer than this? What is setting a limit on this specification?I'd expect < 1 ns rise time.
