Manually Re-Running the Design Rules and Netlist
Check
The design rules and netlist check normally runs automatically, but you
may want to force a final check of the board's integrity prior to saving or
exporting the design.
To do this, select
Design»Netlist and DRC Check
. The results of the
check appear in the
Results
tab of the
Spreadsheet View
.
Cleaning up the Board
Before sending the board for manufacturing, you should remove any open
trace ends and unused vias that have been left on the board.
Deleting Open Trace Ends
Open trace ends are trace segments that do not have any terminating
connections in the design.
To delete open trace ends, make sure the design is open and choose
Edit»Copper Delete»Open Trace Ends
.
This deletes all open trace ends
in the design.
Deleting Unused Vias
Normally, you would delete unused vias after deleting any open trace ends.
To delete any unused vias, make sure the design is open and choose
Design»Clean Unused Vias
to delete all vias that do not have any trace
segments or copper areas connected to them.
Exporting a File
Exporting a file refers to producing an output from Ultiboard in a format
that can be understood by the equipment at the board manufacturer. An
exported file contains complete information describing how a finished
board is to be manufactured. There are many different manufacturing
techniques used to produce printed circuit boards and Ultiboard can
produce a wide variety of outputs to meet these needs.
