Doubt on Interconnect

[surajkashyap]

Hi All,

Suppose there is a long interconnect and we want to reduce the delay by adding buffers. Where should the buffers be added, at the mid point or towards the driver side or the destination side? Why?

Thank you

Hi,
If there is a long interconnect than chances of antenna violations are more so try to place the buffers in such a manner that even the antenna violations is overcome.If you place the buffers too far than also the signal can degrade and your buffer can give a metastable state so keeping these all constructs in mind try to add a buffer. .
