Hello, i am trying to plot with internal waveform graph two signal in a transient simulation. I already do this things several time, but in this testbench is not working. The file is generated, i con plot the signal with terminal, but when i want to load .raw file appear... "raw_read(): failed to open file /home/roberto/.xschem/simulations/tb_schmitt_strigger.raw for reading". Any idea? .temp = 27 .control save all tran 1n 6u plot v(IN) v(OUT) write schmitt_trigger_tran.raw .endc

If yoo want xschem to automatically load the raw file write it with the same name as the circuit:

write tb_schmitt_strigger.raw

instead of

write schmitt_trigger_tran.raw

same problem... I also added launcher arrow with the same name of the file that is wrote

check if

/home/roberto/.xschem/simulations/tb_schmitt_strigger.raw

is existing.

yes is generated. here the file

If you use a launcher set this `tclcommand`:

tclcommand="xschem raw_read $netlist_dir/tb_schmitt_strigger.raw"

in the ngspice testbench use thiw write instruction:

write tb_schmitt_strigger.raw

it's ok the file is ok I can open it:

unbelievable....

check the permissions of the file:

cd ~/.xschem/simulations

ls -l /tb_schmitt_strigger.raw

ls: cannot access '/tb_schmitt_strigger.raw': No such file or directory... strasnge it was always working

sorry my mistake, remove the '/' in front of the file

same results... cannot access

if you can't locate and access the file xschem has the same problem. Try to see where the file is. Run again simulation

sorry typing error... -rw-rw-r-- 1 roberto roberto 1253402 gen 19 21:52 tb_schmitt_trigger.raw

do you run xschem from a terminal? if so at the xschem prompt type this command:

puts $netlist_dir

what is the result?

yes, i go in the folder with the testbench and than i run from terminal. the netlist dir is: /home/roberto/.xschem/simulations

ok at the xschem terminal type this:

xschem raw_read $netlist_dir/tb_schmitt_trigger.raw

Simulation started: execution IDits/xschem/schmitt_trigger] xschem raw_read $netlist_dir/tb_schmitt_trigger.raw Raw file data read: /home/roberto/.xschem/simulations/tb_schmitt_trigger.raw points=6019, vars=26, datasets=1

ok now you can put a graph inside xschem and see waveforms

ok, now is working....

If you do Simulation -> Load/Unload Spice .raw file does that work? This is a toggle, it removes the raw file and then on next click it loads again...

no... it is not working. i removed the arrow. than Simulation -> Load/Unload Spice .raw... still the same error as before

Try to save the schematic, quit xschem and start over again. This is very strange.

the folder, try to run on your machine

AAAARGHHHHH the name of your schematic is tb_schmitt_*`s`*trigger.sch there is an additional s I have done lot of other fixes, i will send you a clean folder in a moment.
