The schematic capture system of the
Bartels AutoEngineer essentially consists of an interactive
Schematic Editor with integrated
and the
Packager program module for converting logical into physical netlists ("Forward Annotation").
The following sections of this manual describe in detail how to use
Packager and
.
3.1.1 Components and Features
Bartels AutoEngineer provides the
Packager program module and the
function for transferring net list data between schematics and layout.
Figure 3-1 shows the design flow of forward and backward annotation using
Packager and
.
Editing SCM sheets with the
Schematic Editor results in a logical net list. The
Packager collects the interconnection information from the logical net list and generates a physical net list ready for layout. The forward annotation process is controlled by the logical library entries defining the assignments of SCM symbols to layout packages and the corresponding pin mappings (see also the description of the
loglib utility program). The
Packager annotates the schematic with the physical pin names to replace the logical pin names and also transfers special information such as pin/gate swap definitions, part attribute settings, power supply pinning, etc.
Layout Net list modifications such as part name changes, pin/gate swaps or part package type assignments must be backward annotated to the schematics using the
function from the
Schematic Editor. Running the
results in a modified logical net list with annotated part and/or pin names on the corresponding SCM sheet.
