Cannot load OSDI library #972

Closed dwarning closed 3 weeks ago

Any of my testbenches show 0 voltages and currents after pressing F8 key. Bildschirmfoto vom 2024-09-29 15-36-05

From what is it dependent? The spice4qucs.cir is written under ~/.qucs/spice4qucs but I see no spice4qucs.cir.dc_op result file. The cir file has not included the pre_osdi file as shown in the schematic and can't simulated.

I cannot reproduce this issue. Everything works as expected on my machine. Please submit your schematic including external Verilog-A source/OSDI files.

The most probably the Nutmeg script is working wrong and model is not loaded. Every nutmeg script is a separate simulation and cannot add the code before the DC sweep. I am wondering if this worked before. You have to put this script in SpiceInit at SPICE netlist sections->SPICE init.

but I see no spice4qucs.cir.dc_op result file.

The datasets are moved to .cache location. See #145 The default is $HOME/.cache/qucs-s

Also the INCLUDE script device may help with the following contents:

.control
pre_osdi file.osdi
.endc

Yes substitute nutmeg script with .spiceinit helps for OP analysis and other simulations too. Bildschirmfoto vom 2024-09-29 16-14-58 Thank you!
