awd = wavescan??

Wavescan is taking 100s of MB of memory and running dog slow and
spawning several java processes. I have disabled it for not and we
are back to awd.

Eric,

We are also not happy with the analog waveform viewers provided by
Cadence.
All the hope over years was put into the new Wavescan which should be
an improvement or at least an adequate replacement for AWD,
but it seems to be not the case.

Also an other issue here is that Cadence does only supports
their proprietary waveform format PSF, which does not allow you
to hook in third party waveform viewers which are more suitable.

A common waveform format in the industry is the
FSDB (Fast Signal Database) format, supported by
many analog waveform viewers e.g. Novas nWave,
Sandwork's WaveView Analyzer and Synopsys Cosmos Scope.
FSDB is original form Novas, but I think it is open now.
FSDB requires less diskspace for the same wave form as PSF
therefore the wave form viewers can open a big file much faster
than AWD on PSF.

There is a PCR at Cadence that the Affirma Analog Environment
should support the FSDB format #650290, but I think there is
no action on it.

Just for completion a funny thing, UltraSim does or at least
did support FSDB.

Instead of using either wavescan or awd, with the significant issues
that have been listed in this thread, you can use the Undertow
waveform viewer directly with your PSF binary or PSF ASCII files. The
major advantage of using Undertow is the speed of loading and viewing
your waveform files. Undertow will load even 2 gigabyte files very
quickly and allow the user to view the waveform data for any signal
almost instantly. Undertow has one of the most complete set of analog
analysis features available on the market today, and includes the
built in scripting language, Perl, which is the standard scripting
language in use in the EDA market today. Undertow also has a DFII
integration environment that allows users to connect their Composer
schematic window directly to Undertow, and select signals either
analog or digital directly from their Composer schematic, in order to
view the data in their PSF binary files. Designers who would like to
get the Undertow waveform viewer and analog analysis environment can
down load this software at no cost from www.veritools.com and request
a license directly from a page on this web site.
