EDI/nanoroute process antenna problem

themperek 
Hi,

Because of university license we do not have support so I posting my problem here.

It looks nanoroute DRC engine is calculating area of metal different way then EDI.

After "pdi verify -process_antenna" I am getting thousandths of violations 
(interestingly this happens only after 2nd and further routing during optimization).

After "verifyProcessAntenna" I am getting only few violations.

Example for report file:
nanoroute:
net net_47 (2) 
    VIO:  top/U6 (AOI22X1) A1 on M1 :
           PAR / Ratio (723.4206 / 298.0000) .
           Area(49.1926) S.Area(7.5976) G.Area(0.0680) D.Area(0.0000)

EDI:
  net_47 (2)
    top/U6  (AOI22X1) A1
      [1]        M1:  Area:    0.26  S.Area:    0.86  G.Area:    0.07  D.Area:    0.00
                Fact:    1.00     PAR:    3.84   Ratio:  298.00       (Area)
                Fact:    1.00     PAR:   12.69   Ratio:    0.00       (S.Area)
                                  CAR:    3.84   Ratio:    0.00       (C.Area)
                                  CAR:   12.69   Ratio:    0.00       (C.S.Area) 

EDI/nanorute: 9.1 (in 8.1 it looks the same).

Does anyone has any idea what is going on here?

     The "pdi verify" stuff is old. Use verifyProcessAntenna.
