ngspice for parallel simulation

There is now a (still very experimental) example available for running several ngspice shared library invocations in parallel, simulating a circuit partitioned into pieces in a parallel and synchronized manner.

Please have a look at http://ngspice.sourceforge.net/parallel.html for further information.

ngspice as a shared library

I have made an update to the ngspice shared library interface.
Three new callback function have been added for transient simulation synchronization.

The callback function interface has been changed slightly by adding a identification number. You will have to adapt your existing code to this feature.

ngSpice_Init_Sync() has been enhanced to transfer the callback pointers and the ident number.

Please have a look at the actual ngspice manual, chapter 19.6, for details.... read more

ngspice as a shared library

ngspice may be compiled as a shared library,
offering full control over the simulator by a
calling process.
Please have a look at
