ITER CX COEFF_NUM

##  Expected RobustVerilog parameters:

##  SWAP ORDER val       - order of FIR

##  SWAP COEFF_BITS val  - precision of coeeficients (bit num)

##  SWAP DIN_BITS val    - precision of input data (bit num)

##  SWAP MAC_NUM val     - number of multiplayers (determines architecture)

//  Built In Parameters:

//  

//    Filter Order              = ORDER

//    Input Precision           = DIN_BITS

//    Coefficient Precision     = COEFF_BITS

//    Number of serial FIR sons = MAC_NUM

//    Number of multiplayers    = MAC_NUM

//    Architecture              = ARCH

//    Sum of Products Latency   = LATENCY
