We have used verilint in the past here at work, and also just discovered the large

price increase, (to 47k).  I guess the big reason to use it now is to make sure
that the
code you have written will synthesize to what you wanted.  As we have already
seen,
all simulators are not created equal, and most are not exactly what the
synthesized
si would be.  I guess the theory is that verilint is so strict that it won't allow
you to
use questionable constructs at all, to things will synthesize the way you expect
them
to.

I think the open source community could "serve Mankind, etc" very well by
developing
a good verilint replacement.  Something that is highly configurable (allows user
to ignore
classes of warnings, or ignore warnings in a block of code) and free could find
its way
into many design houses not willing to pay 47k for a lint. (glint ;-)

my $0.0237, adjusted for inflation
