Concerning the fact that the design of contemporary integrated circuits (IC)
is practically impossible without using sophisticated Electronic Design
Automation (EDA) software, this paper gives some interesting thoughts and
considerations about that issue. As technology processes advances on year
basis consequently EDA industry is forced to follow this trend as well. This,
on the other hand, requires IC designer to frequently and efficiently
accommodate to new working environments. Authors of this paper suggest a
method for high level circuit analysis that is based on using common (open
source or low cost) circuit simulators but precise and fast enough to meet
requirements imposed by demanding mixed-signal blocks. The paper demonstrates
the proposed EDA procedure on an example of second order ?? modulator design.
It illustrates considerable simulation time saving which is more than welcome
in a world of analogue and mixed-signal design.
