[Numerically controlled oscillator](https://en.wikipedia.org/wiki/Numerically_controlled_oscillator) (NCO) in Verilog RTL
Configurable hybrid implementation:
* complex output {Im, Re}
* Integer (2's complement) implementation
* Pi/4 Look-up table stage
* N2 - CORDIC stages
* N3 - Dynamic Rotation CORDIC stages
## Parameters
* WD : data width (per component)
* SCALE : fixed point magnitude of the output signal
* WA0 : phase accumulator width
* WA1 : Look-up table bits
* WA2 : bits for the CORDIC stages
* WA3 : bits for the Dynamic Rotation CORDIC
