Backannotation to Multisim
Backannotation is a highly automated process which ensures that
modifications made to an Ultiboard design are transferred to the board’s
schematic in Multisim. This process helps keep your schematics and board
layouts consistent with one another.
Backannotation is an important feature of CAD software. Part renaming or
removing cause inconsistencies between the schematic and the PCB
design. Backannotation can overcome these inconsistencies. To
backannotate, Multisim reads the log file in which Ultiboard reports all the
changes that are made to a PCB. The log file has the same name as the
project, but with the extension
.log .
Not all changes that are made to the PCB can be backannotated to
Multisim. The following changes can be backannotated:
• part removing
• part renaming
• netlist renaming
Complete the following steps to backannotate your revisions:
1. Save and close your design in Ultiboard.
2. Open Multisim.
3. Follow the Back Annotation procedure documented in the Multisim
User Manual.
Mitering Corners
Corner mitering is used to reduce or remove sharp angles for placed traces
by creating 135° angles in their place. This is important for manufacturing
purposes. You can apply corner mitering to the entire design or just the
currently selected traces.
