SPICE DIGSRC model giving me problems

[k7michal]

Hi everyone, thank you for your help. 

I'm just getting started in SPICE modeling. Watched the 1H28m primer... played with analog and digital examples and I keep running into this issue which I've narrowed down to 1 particular model.

For some reason I can't get DIGSRC to work right.. so I made a separate .sch program with just that model and a voltage probe and after setting up the table and hitting simulate, it just time elapses on and on and on until there is a time out. 

I hope that I'm just not doing something correctly. 

Thank you.

 im having the same problem did you figure it out?

There might be a problem with the ngspice dsource model used in the adder.sch: It will not accept a file path with spaces.

EAGLE installed in "EAGLE 9.6.2", the simulation of adder.sch does not work. Copying the folder "C:\EAGLE 9.6.2\examples\projects\examples\ngspice" to C:\EAGLE\ngspice and opening C:\EAGLE\ngspice\Digital\adder.sch in EAGLE, simulation is up and running.

I will care for this bug in ngspice.

I have uploaded a fix to ngspice git branch pre-master.

The fix will be available in ngspice-35, to be released by end of July.
