overcon gcell

this congestion table has two parts,, one part being above the horizental line gives information about the locations where congestion is there i,e no of tracks is less than the demanding,, and the number remain gives,, how many tracks is needed in that location and the next number no of locations and its percentage in both horizenatal and vertical tracts cntH stands for Horizantal and cntV for vertical
similarly the below pat is for locations where no congestion is there or no of tracs are more than demand


HOPE IT HELPS U ... feel free to trigger qns

encounter how to route congestion

Hi,
I want to know one more thing....
What is the significance of -1 to -20 in the log file


regards,
KAdhan

 

[raju3295]

open gui command soc encounter

this number says that many tracks are required in that location i,e -1 means no of tracks needed in tat location is one more than the no of tracks are avaialable.

Added after 1 minutes:

looks like ur design is congested lot,, need to see the placement of modules or open the gui and see where where the congestion is coming.
