Hello! I am writing extension for control of ngspice in form of shared library. My question is - what is the safe sequence for unloading shared library without memory corruption? My sequence is: 1. Tries to gracefully shut down background thread by bg_halt command, wait for the BGThreadRunning callback with some timeout (there is also checks that wait issuing bg_halt until thread is launched, if call to unload arrive at that transition time) 2. Send quit command to ngspice 3. Wait for ControlledExit...

Right after posting, I realized that I can just put quit command right after the write command...

Hello! It may sounds strange, but my question is: Is it possible to override raw file that is specified with command line option -r in batch mode? For example, I want to save raw file inside .control section with write command under the same name as file specified with -r option, but with different vectors. If I just add write command, the file later is being overwritten by standard raw file. I know that I can just not specify -r option, but in my specific application, it is difficult to know if...

As far as I know, there is no such feature now. In theory, it could be handled with compiling Ngspice as a shared library and control it precisely from external script that detects convergence issues, change tolerances and resume simulation, but still need confirmation from more experienced users
