 PCBMod
provides you with a complete and efficient program
package for layout planning and layout analysis
of printed circuit board designs. Additionally
PCBMod fits easily into your familiar design flow.
Its distinguishing features are the automatic
extraction of arbitrarily shaped copper structures
on the board while at the same time it can be
directly included into common PCB design environments.
PCBMod includes two- and three-dimensional field
solvers which enable you to make exact statements
about the quality of layout structures of your
board design.
 The
program concept realized in PCBMod takes into
consideration the special demands a circuit designer
has on a software tool used in industrial development
of printed circuit boards:
- multiple
possibilities of usage in all phases of layout
generation
- interfaces
to several PCB-frameworks
- simple
integration into your familiar design flow
- exact
and quick methods of calculation
- flexible
configurability
- comfortable
user interface
 For
the automatic data input we offer interfaces to
the Mentor Graphics Board Station and to Zuken-Redacs
VISULA and CADSTAR (in development). The output
files generated by individual program sections
make possible a complete simulation of the examined
structures as well as their graphical representation.
The Spice-compatible analog simulator included
in the users design environment is used for the
signal analysis. Here special functions and models
of Eldo and Saber (in development) are supported.
A fundamentally new development is the consideration
of arbitrarily shaped copper areas in the layout
extraction.
Not
only continuous groundplanes but also an unlimited
number of partial ground planes (area fills) which
are widly spread in analog circuits are considered
in the calculations. This special ability makes
PCBMod outstanding in the following fields of
use:
- detailed
analysis of analog PCB layouts
- generation
of a ground concept of a circuit
- guarantee
of signal integrity
Program
flow phases of PCBMod in automatic extraction:
 Selection:
The user selects the layout structures that one
plans to analyze within the PCB design environment.
This simplifies the selection of arbitrary lines,
area fills, pins, vias and ground planes by mouse-click.
 Layout
analysis:
Collection of the selected structures, consideration
of printed circuit board technology, reading in
of user specific parameters.
 Extraction:
Analysis of layout geometries, inclusion of neighbouring
unselected elements with adjustable detection
threshold, building up of a logical connecting
structure between the extracted elements, data
processing depending on the selected way of extraction.
 Modelling,
calculation:
Activation of the according two- and three-dimensional
field solvers, preservation of the logical net
nodes assignments.
Data
output: Generation of simulation models
(Spice substitute circuits) including intermediate
nodes, several ways of matrix representation,
graphic output.
PCBMod
includes a large number of predefined modelling
and calculation possibilities for the configuration
of the automatic layout extraction:
- line
capacitances and inductances
- wave
impedances
- line
discontinuities
- capacitances
and inductances of arbitrary 3D structures
- current
distributions
The
user is supplied with extensive possibilities
for manual generation of structures to be modelled
and calculated.
