Analog and digital mixed. I seek this information for friend who wishes to 
start a project and we discussed this part.

Actually, understanding that the simulator will need to know the way IC's 
operate (and which cant be all expected?) was where this second requirement 
came up.

The IO pins can be setup with a combination of resistors, capacitors, diodes 
etc connected to VCC and/or GND. This way any new IC can be supported 
without explicit support for it from the backend. I don't know how *fast* 
this scheme would operate but with this, analog only simulation would be 
sufficient(?).
