Lattice Nexus devices using Reveal: no output from LVDS IP

Description: 
While debugging your Radiant design using Reveal, users may observe that there is no output from their LVDS IP. 

 

Solution: 

When Reveal is inserted in Nexus devices, on certain designs, the GSR net gets assigned to a reset signal that may behave incorrectly. Hence causing Reveal and possibly other circuits not to function properly. 

 

To resolve this, please disable the GSR option in the Strategy Settings: 





Recompile and see if both Reveal and LVDS outputs start working.
