B-12 Timing Diagrams and Outputs
determine approximately where the error occurred by looking at
the diagram and noting which of the displays are as you expected
them to be.
The graphic timing diagram outputs can be saved in files or sent to
a laser (HP LaserJet) printer, or an equivalent, as well as a
dot-matrix printer which supports raw raster dumps.
The timing analyzer needs two printer shell variables setup to
function properly PRINTER and GPRINTER. The PRINTER
shell variable should be set to "lp -s" with the commands
PRINTER="lp -s" <RETURN>
export PRINTER <RETURN>
or an equivalent command. The PRINTER variable determines
where all the ASCII displays of the timing analyzer are "piped"
when a "copy < specification> to printer" command is entered.
The GPRINTER variable should be setup to "lp -or -s" with the
command
GPRINTER="lp -or -s" <RETURN>
export GPRINTER <RETURN>
or an equivalent command. The GPRINTER variable determines
where the graphics display of the timing analyzer is "piped" when a
"copy timing_diagram to printer" command is entered.
Finally graphics dumps tend to create rather large files. Therefore,
if you keep your graphics outputs in files you may want to limit the
number that you keep.
Your system administrator may need to adjust the model for your
printer to include the raw option (r, raw). A complete example of
an appropriate printer model can be found in the manual.
