MIF_NOI is not yet supported by any code model, so
MIF_AC is used (code models behave like in ac mode,

Change output event setup in evtload.c so that, when making an event call
to a code model, there is no longer a reference to the value of the event
at the head of the free list. That allows all such free lists (with the
same data type) to be combined, probably improving performance.
This is in preparation for full implementation of inertial delay for
digital nodes.

Add inertial_delay=true to .model statements generated when U* instances in PSpice library subckts are translated to Xspice. Any other Xspice A* digital instances might have different inertial_delay settings in their models, so potentially there could be a mixture of delay types. For example, if a user wishes to model a DLYLINE using a d_buffer with inertial_delay=false and equal rise/fall delays.

The intent now is to rely on a variable setting in .spiceinit to control the use of inertial delay XSPICE digital models. This will apply to U* instances in subcircuits which are translated to XSPICE.
