user362: I have heard, therefore I am yet to discover in Tipitaka, that to achieve certain stream winner stages, one needs to fulfill paramithä. Could you please give me the names of some sutta which I can read further on this (or the Tipitaka vagga / section).

Thanks in advance! 

user8157: The doctrine of 'paramithä' is not found in the suttas but found in late canonical books and post-canonical commentaries (Wikipedia). 
However, the basic requirement for giving (dana) & morality (sila) to be excellent or 'higher' ('parama') than ordinary is found in the suttas. 
For example, AN 7.49 lists seven types of giving (dana), where six types of giving are based in views & self-views that can lead to suffering. Where as the 7th kind of giving, namely, giving for the purpose of beautifying & supporting the mind (citta) rather than giving to beautify & support the 'self' (atta) is said to lead to non-returner. Therefore, such giving can obviously lead to stream-entry. 
Also, since the end of MN 118 states each of the seven factors of enlightenment has 'giving up' ('vossagga') as its primary quality, this shows the ability to give open-handedly or unselfishly is an important factor for stream-entry. 
As for morality (sila), many suttas (such as SN 55.1 & MN 6) make it clear that morality must be higher than ordinary for the attainment of stream-entry.

I think that SN 55.2 implies perfection of Sila.
People say that Dana parami is an essential beginning, for example here ...

Giving (dana) is one of the essential preliminary steps of Buddhist practice.

... but I don't know a sutta where it's named as a characteristic of a stream winner.
I wonder where the talk about practicing paramithä came from. Have you encountered people or books that speak of requiring paramithä to become a stream winner?
There are a couple of talks on Access to Insight.

The Ten Perfections
A Treatise on the Paramis

I didn't find any (after only a brief search) on dharmafarer.org
My theory is that "perfection" isn't a doctrine which is talked about in the suttas.
The "Ten Perfections" for example starts by saying,

Each path was defined as consisting of perfections (paramī) of character, but there was a question as to what those perfections were and how the paths differed from one another.

So I guess those doctrines (the doctrines about "perfections") were developed after the suttas.
The "Treatise" talks about the sequence in which they should be developed, and how to practice them and so on:

Here "sequence" means sequence of teaching. This sequence is rooted in the order in which the paaramiis are initially undertaken, which in turn is rooted in the order in which they are investigated.

It finishes with:

Their fruit is, in brief, the state of perfect Buddhahood.

The introduction says,

The "requisites of enlightenment" are the paaramiis themselves, the main topic of the treatise. The word paaramii derives from parama, "supreme," and thus suggests the eminence of the qualities which must be fulfilled by a bodhisattva in the long course of his spiritual development.


So far as I know, when Theravada talks about the Four stages of enlightenment (starting with "stream winner") it's more usual to talk about the "fetters" which are overcome, rather than about "perfections".

user10293: Please don't make any confusion. Only Buddha-to-be, pacceka Buddha and chief disciples of Buddha need parami to fulfill. No such need to be a stream winner. Having no huge negative karma i.e., killing the parents, causing the blood flow from Buddha, causing disunity in Sangha, and killing an arahat, and having intent desire to be a stream-winner, keeping faith in triple gems, having good meditation master(preferably at least a stream winner), and oneself also work hard through insight meditation with sila and Samadhi,  all these  surely lead to be a stream winner. No parami to be a stream winner.
