Hi, im new to vhdl coding. I want to implement a dqpsk precoder using two D flip flops.
however,im not able to synthesize the code successfully. It shows some errors.
The code and diagram are attached. the errors found are:
ERROR:HDLParsers:3312 - "C:/Xilinx/10.1/ISE/MAIN/mainproj/precoder.vhd" Line 54. Undefined symbol 'c'.
ERROR:HDLParsers:1209 - "C:/Xilinx/10.1/ISE/MAIN/mainproj/precoder.vhd" Line 54. c: Undefined symbol (last report in this block)
ERROR:HDLParsers:3312 - "C:/Xilinx/10.1/ISE/MAIN/mainproj/precoder.vhd" Line 55. Undefined symbol 'q'.
Why isn't the code getting synthesized successfully?
i've marked line 54 and 55 in the attached file
