Hello Sandrine,
I'd like to write a script code that automatically changes the parameters
of the schemmatics in xcircuit example that does this: g / pMOS $ /
s/analoglib3 :: pMOS / analog :: PMOS2 / g.
Are possible? If yes how can I do it.
First, please note that these are not "parameters". . . they are the
actual objects being used (in SPICE, the model name would be a parameter,
but in a schematic editor, typically there will be a different symbol
used for different models).
The following simple unix shell script will make the substitution:
#!/bin/sh
cat ${1%.ps}.ps | sed -e "/pMOS\$/s/analoglib3::pMOS/analog::pmos2/g" \
> ${1%.ps}_new.ps
Save this script as, say, "mod.sh", then do "chmod a+x mod.sh"; then
you can do (using your original example file) "mod.sh Master2.ps".
This will create a new file "Master2_new.ps" with the substitutions.
However, this will create an invalid postscript file, because the
file now makes reference to a symbol "analog::pmos2" that is not
defined in the same file.
A better way is to use xcircuit in batch mode. This requires the latest
revision of xcircuit-3.8, because I only put in the command to replace
one object with another after your original email. That script would
look like this:
#!/bin/csh -f
if ( $# == 0 ) then
echo "Please specify an xcircuit filename."
exit
endif
xcircuit -noconsole -nowindow << EOF
page load $1
set p [object parts]
foreach e \$p {
if {[element \$e type] == "Object Instance"} {
set n [element \$e object]
if {\$n == "analoglib3::pMOS"} {
element \$e object analog::pmos2
}
}
}
deselect
page save ${1:r}_new
quit
Save this script as, say, "mod2.sh", then do "chmod a+x mod2.sh"; then
you can do "mod2.sh Master2.ps", and it will produce a valid output
file called "Master2_new.ps" with all the objects correctly defined
within the same file.
This is worth posting to the xcircuit-dev email list because I don't
think there are a lot of people who know how to write batch processing
scripts for xcircuit. Probably there are a lot of people who don't
even know that it's possible to write batch processing scripts for
xcircuit. I should write a tutorial on it. . .
Hopefully this solves your problem.
Regards,
Tim
