## NAME

nlwav − manual page for nlwav (netlist) 0.1

## SYNOPSIS

nlwav [OPTION] ... [FILE] ...

## DESCRIPTION

Convert netlist log files into wav files.

## OPTIONS

−f, −−format=wav16s|wav32s|wav32f|vcda|vcdd|tab

output format. Available options are wav16s|wav32s|wav32f|vcda|vcdd|tab.

| wav16s |  | : multichannel wav output 16 bit signed |
| wav32s |  | : multichannel wav output 32 bit signed |
| wav32f |  | : multichannel wav output 32 bit float |

vcda : analog VCD output

vcdd : digital VCD output tab : sampled output Digital signals are created using the −−high and

−−low options

−o, −−output=Value

output file

wav options:

These options apply to wav output only

−r, −−rate=Value

sample rate of output file

−a, −−amp=Value

amplification after mean correction

−−lowpass=Value

lowpass filter frequency. Default 20000 Hz.

−−highpass=Value

highpass filter frequency. Default is 20 Hz.

−−hpboost

enable highpass boost to filter out initial click.

vcdd options:

These options apply to vcdd output only

−u, −−high=Value

minimum input for high level

−l, −−low=Value

maximum input for low level

tab options:

These options apply to sampled output only

−s, −−start=Value

time when sampling starts

−i, −−increment=Value

time between samples

−n, −−samples=Value

number of samples

General options:

These options always apply

−v, −−verbose

be verbose − this produces lots of output

−q, −−quiet

be quiet − no warnings

−−version

display version and exit

−h, −−help

display help and exit

## EXAMPLES

./nlwav −f vcdd −o x.vcd log_V*

convert all files starting with "log_V" into a digital vcd file

./nlwav −f wav16s −o x.wav log_V*

convert all files starting with "log_V" into a multichannel wav file (16bit, signed)

./nlwav −f tab −o x.tab −s 0.0000005 −i 0.000001 −n 256 log_BLUE.log

convert file log_BLUE.log to sampled output. First sample at 500ns followed by 255 samples every micro−second.
