best way to use SWDIO and SWDCK

Hi everybody, i'm working on a custom board and experiencing a strange problem: if the two cables of SWDIO and SWDCK (they go from a stm32f4 discovery board to my board) are close Keil doesn't recognize the cortex device, if i keep them well separated everything works fine.
there is a way to have a better performance of this serial debugging feature?
in my layout there is more than 1 cm between the two traces so i don't think that is a problem of crosstalk on the board.

thank you so much for your help.
have a good year
