The following data is used in implementing various enhancements made to the
|
|
simulator. The main struct is dynamically allocated in ckt so that incremental additions
|
|
can be made more easily without the need to recompile multiple modules.
|
|
Allocation and initialization is done in CKTinit.c which should be the only
|
|
module needed to recompile after additions are made here.
