+Mixed IO types  
+* This circuit contains a mixture of IO types, including  
+* analog, digital, user-defined (real), and 'null'. 
+*  
+* The circuit demonstrates the use of the digital and 
+* user-defined node capability to model system-level designs 
+* such as sampled-data filters. The simulated circuit 
+* contains a digital oscillator enabled after 100us. The 
+* square wave oscillator output is divided by 8 with a 
+* ripple counter. The result is passed through a digital 
+* filter to convert it to a sine wave.
