SDAccel Compilation errors(LUT3 cell missing connection)

Jump to solution

I am trying to compile the RTL Kernel developed in the SDACCEL but I get the following compilation error. Can someone tell me how to get around this issue and fix it so that the sdaccel flow goes thorugh.

Below is the error.

ERROR: [VPL 31-67] Problem: A LUT3 cell in the design is missing a connection on input pin I2, which is used by the LUT equation. This pin has either been left unconnected in the design or the connection was removed due to the trimming of unused logic. The LUT cell name is: xxxx/dynamic_region/interconnect_axilite_user_slr1/m03_couplers/m03_regslice/inst/aw.aw_pipe/m_valid_i_i_1.

 

Thanks and appreciate the help.

You need to check your source code to find the reason why the input of the reported LUT3 is optimized.

The above work can be done in Vivado and you can cross-probe in your code and the netlist.
