cell orientations in physical design

[akshit468]

Hello,
i see different cell orientation naming conventions like N,S,FN,R0,MX180 etc.. can anyone please help me with all the naming conventions and their significance in representing a cell orientation?

thanks in advance

Hi,

I don't have the documentation of CAD tools with me but :
R0, R90,R180,R270 : rotations of 0/90/180/270 degrees clock wise
MX : mirror around X axys
N,S,E,W : Nort, South, East, West - I don't think this apply to orientation, but rather to (relative) position

Best regards
