Real to Fixed-Point Converter (RTOFXT)

Real to Fixed-Point Converter (RTOFXT)

Property	Description	Units	Default	Range/type
outW	Word length of the output fixed-point number	None	32	[1, 32]/Integer
outD	Precision of the output fixed-point number	None	0	[1, 32]/Integer
ovf	Overflow characteristic: 0 for wrapped, 1 for saturate, 2 for zero saturate	None	0	[0, 2]/Integer
quant	Quantization characteristic: 0 for truncated, 1 for rounded, 2 for truncated 0	None	0	[0, 2]/Integer
ArithType	Arithmetic type: 0 for signed, 1 for unsigned	None	0	[0, 1]/Integer
Rin	Input impedance	Ohm	Inf	(0, Inf]/Real
Rout	Output impedance	Ohm	0	[0, Inf)/Real
Ports
Input	Input signal (floating point real number)
Output	Output signal (fixed point real number)

Limits

1. outW > outD for signed arithmetic

Notes

This model converts the real floating point input signal to real fixed-point signal. The output format is set by the user specified parameters: outW, outD, ovf, quant and arithtype, where ovf defines the overflow characteristics, quant defines the quantization characteristics and arithtype defines the arithmetic type. The following plot shows the relationship between the word length and the precision.

Netlist Form

RTOFXT:NAME n1 n2 [outW=val] [outD=val] [ovf=val] [quant=val] [arithtype=val] [Rin=val] [Rout=val]

Example

RTOFXT:1 1 2 outW=16 outD=4
