I'm using SoC Encounter for my implementation. Everything is fine except [verifyConnectivity report], I have 5 antenna problems : like
Net DATA_I[7]: antenna at (41.067500,182.975) on layer M3
NET KEY_I[4]: antenna at (47.0575,11.4425) on layer M3
NET KEY_I[4]: antenna at (44.41,182.815) on layer M3
NET KEY_I[5]: antenna at (46.11,112925) on layer M3
NET KEY_I[5]: antenna at (43.2625,182.98) on layer M3

I tried manually to adjust the wires but with no benefit, I also tried the repairing process antenna violations commands with NanoRoute but also with no benefit.

How can I fix these 5 antenna problems in those 3 nets to have a correct implementation before going to Physical Verification and Post layout Simulation?

-I attached screenshots of the nets in their antenna locations (As you see the location like reported is at when M3 is reaching the via with M2)

you can add diodes if your library has one.
