// ABSTRACT: Verilog simulation model for IIR filter with dynamic coefficients
|
||||||
|
//
|
||||||
|
// MODIFIED:
|
||||||
|
// Doug Lee 06/02/2008
|
||||||
|
// Fix for STAR#9000245949
|
||||||
|
// data_out and saturation results were wrong
|
||||||
|
// compared to synthetic and VHDL simulation
|
||||||
|
// models in a specific negative number
|
||||||
|
// boundary case. Re-wrote rounding/saturation
|
||||||
|
// function to resemble VHDL simulation model
|
||||||
|
// approach.
|
||||||
|
//
|
||||||
|
// Zhijun (Jerry) Huang 02/12/2004
|
||||||
|
// Changed interface names
|
||||||
|
// Added parameter legality check
|
||||||
|
// Added asynchronous reset signal rst_n
|
||||||
|
// Added optional output register controlled by parameter out_reg
|
||||||
|
// Added X-processing
|
||||||
|
// Fixed verilog analysis warning about zero multiconcat multiplier
|
||||||
|
// Fixed verilog analysis error about negative array index
|
||||||
|
// Fixed logic errors with saturation and negative/positive handling
|
||||||
|
// Fixed logic errors with feedback_data when feedback_width > data_out_width
