pyNgSpice

Holger Vogt ace47103e7 Search path for .lib and .include has been enhanced to read complete or partial paths from environmental variables. The env variable names have to start with '$' as the first character after the .inc or .lib token. Two consecutive env variables are possible. They are read each until directory separator '/' or '\\', or if none is found, until the end of the line. In this case the filename has to be included in the env variable. A .lib line may look like .lib "$ENVS1\$ENVS2/libraries\sky130_fd_pr\latest\models\sky130.lib.spice" tt If an env variable is read successfully, a ngspice variable with the same name (without leading '$') and contents is defined for use in a .control section.		2 years ago

cider	When Cider models are present, a normal batch mode sp_shutdown (for example, ngspice -b cmosinv.cir) will call com_quit(NULL). This cleans up so that valgrind will find no leaks in Cider devices after sp_shutdown. To disable this feature, set the environment variable CIDER_COM_QUIT="OFF". Even though it really does not matter that Cider memory is cleared just before exit, it makes it cleaner for valgrind checks.	3 years ago
