When trying to generate a physical constraints file for hdmi application lvds25 option is not on the list for hdmi pin banks.
How example projects that use the hdmi channel is doing PnR I still don'T get it.
I tried copying a cst file from an example and making example project my own project by adding necessary .v files but result is always the same:
tmds pairs either become cmos33d or when selecting lvds25e, clk and reset pins needed to be lowered to 2.5V as well for PnR.
However that is not the case at the examples provided that using HDMI.
(they have some pins of same bank at lvcmos33 and tmds pairs at the same bank as lvds25)
