Hello Barry,
Thank you. I tried a workaround with your suggestion, but I wasnt quite successful in that.
After I break the conversions, I landed up with other errors.
I am somewhere messing up the the data types and arrays.
Its the same error
Simulation error:

Hello all,
While doing behavioral simulation, there is an error which says '
and
All the vector length used here is 4(3 downto 0)
Two doubts:
1. The range says 0 to 2147483647 , but I am using only 0 to 15(2**4)
2. The value -3. Sine
Please do suggest if there is any more changes for...
Hey,
The simulation gives a warning error of "
[VRFC 10-4940] 'sine' remains a black box since it has no binding entity ["C:/Users/L/.../L.srcs/sim_1/new/L_tb.vhd":35]"
So at simulation output also has 'U' value.
I am using Vivado 2019.2, library is set to 'work' , file type is 'VHDL' and it...
Hello all,
Direct Digital Synthesis (DDS) has frequency switching ability . While trying to implement the DDS in VHDL, I got confused with the frequency switching ability of DDS. For example, I have implemented the sine wave which generates multiple waves from testbench defined. But how do I...
I am trying to generate sine value for DDS, but I have error during synthesis. I have included ''ieee.math_real.all''
