Subject: Changing Designer's Minds About Using BC With COSSAP
John,
I've been dealing with Behavioral Compiler since the beginning of last
year. In our CAD/support department we are aware that there is or will be
a need for behavioral synthesis and related methods: design complexity
keeps increasing and design time must decrease. We've done an evaluation
on an existing design (reimplemented that) and the results were ok (it
took quite some efforts at that time), but not in a manner that we really
could convince the designers in changing their design methodology.
Currently we're setting up a new project (again a reimplementation) where
we hope to see a real improvement in our design flow: Cossap (which is
widely used here) will generate behavioral VHDL from the algorithmic
design implementation. Behavioral Compiler will "do the rest". There is
no need anymore to reimplement the Cossap design on RT-level. As a second
step we will see how Behavioral Compiler has improved since the latest
versions. The designers in this project are willing to change to an
improved design methodology.
Still I think designers need their time to switch to new methodologies.
Some years ago it was similar as they changed from schematic entry to RTL
(V)HDL design.
