2015.3 Vivado Synthesis - ERROR: [Synth 8-27] complex assignment not supported.


I am receiving the following error in Vivado Synthesis:

ERROR: [Synth 8-27] complex assignment not supported [/.../top.vhd:120]

An example of the code I am using is below:

next_buf(write_count_i_v+conv_integer(wclk_write_bit_number)-1 downto write_count_i_v) <= wclk_din(conv_integer(wclk_write_bit_number)-1 downto 0);

Is this type of assignment supported by Vivado Synthesis?


This type of assignment is not supported. Please modify your code as necessary.

It is recommended to reduce the dynamic indexing in the assignments in cases such as this.
