Brian Taylor 6500caeba1 Now that checks on actuals and formals have been fixed for X* instances, some older PSpice libraries will not translate correctly in psa mode. This commit removes unnecessary power and ground nodes from X* instances of subcircuits where the nodes are optional. These X* instances occur within the body of another subcircuit which is being translated. MicroCap libraries that we can translate in ngspice do not have such cases. To enable the removal of the power and ground nodes, set ps_global_tmodels=1 in .spiceinit. This is not set by default since an extra pass through the circuit word list is necessary to find the subcircuits whose instances do not require power and ground node removal. Without enabling this feature, errors reporting too many parameters may be reported. 1 year 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
