What is the H-Tree and what does it do?

[anishjp]

Hi Everybody,

Can anybody help me out to find what is this 'H-Tree'.

 

[ericyuan]

H Tree

clock tree structure....
maybe it is a good way to balance the skew...

H Tree

Yes ericyuan is right....It is basically a structure of a clock tree which is called as Binary H-tree..This algorithm is used in cadence tool called as Soc encounter..to balance the skew....

H Tree

by H tree,main moto is to equalise toplevel insertion delay

H Tree

to balance the clock skew h tree structure is used

Re: H Tree

When you routing the clock net, due to net delay there may be a skew between the flops.. To avoid the skew, we use H-Tree structure to implement clock routing.
