Xilinx xfft v7.1 IP 下 shift_ram.vhd源码,以fft为design top进行DC综合时报错:
Error: xfft_v7_1/shift_ram.vhd:1112: The lhs width=16 does not match the rhs width=1 of the assignment statement. (ELAB-992)
shift_ram.vhd:
源码初始为:
port map(
D => Dint,
CLK => CLK,
CE => CE,
Q => Dint);
调整改成第一张图所示,仍报相同错误,调试中有时错误信息变成:The lhs width=1 does not match the rhs width=16
