newbee NGSpice KiCAD question
(1/1)
Pannenkoek_met_een_lampje:
Hello just trying to learn NGSpice, I use KiCAD to make the schematic. I did a few things of the following to check if it works:
http://ngspice.sourceforge.net/ngspice-eeschema.html
the filter and transistor schematic works so thats great. So I though lets try a comparator with 3 opamps. When I try to RUN this in NGspice I get:

Circuit: KiCad schematic
Too many parameters for subcircuit type "lm324" (instance: xxu1)
Background thread stopped with timeout = 0
Reducing trtol to 1 for xspice 'A' devices
Doing analysis at TEMP = 27,000000 and TNOM = 27,000000
No. of Data Rows : 11





my lm324.mod file looks like this:

Can anyone tell me what might be wrong? This might be very simple thing but I am  new with NGSPice so some help would be great

thank



SiliconWizard:
Can you post your KiCad schematic file? Or just the Spice circuit file for that matter.

Most likely the opamp symbol you're using has more pins than the 5 ports declared in the LM324 subcircuit and the extra pins end up in the spice netlist.
