Lattice MachxO3 - LVDS invertieren

[Holger K. (holgerkraehe)]

Hallo zusammen

Ich habe bei meinem Board ausversehen P und N vertauscht.
Gibt es eine möglichkeit, die Polarität der LVDS-Paare direkt zu 
invertieren?

Danke!

In Hardware nicht, aber in Logik:

internal_signal <= not external_lvds_signal;
