I am working with the cyclone V device.Currently i am processing the lvds signals.

The major problem is, i cannot route the input lvds signal between the input to the LVDS_RX IP and input to the lcd externally connected at the same time.Either as input to the lcd or IP is possible....

I am connecting the LVDS output from a board A1 to the custom board with FPGA 5CEBA2F23C8. This is then transmitted to HDMI interface. I also need to loopback the LVDS data coming to the custom board to an LCD. But while compiling in Quartus some errors are occuring in 'Fitter( (Place and Route)'

The following are the error messages:

Error (170143): Final fitting attempt was unsuccessful
