difference between pins and feed through

[research235]

what is basic difference between pins and feeds. at top level physical design design.

i guess u are referring to ports of a block or pins of a hierarchical block in top level physical design,
pins are which have timing path or connected to some sequential flops in the block,

where as feedthrouhs are which dont have any valid timing path inside the block, these are only a direction in2out connections, with some buf/inv cell to meet the transition

Feedthru pins are analog pin routed manually in physical design.

Feed Through:-Feedthrough is nothing but a net will be going through your block but it's lunch and capture flop will not be in our block that is called as Feed Through
Pinin is nothing but a connecting point
