LEDS

This page tries out ways to model simple blocks of logic doing a digital monstable. Each IC has an input and output and other logic.

An LED is connected to the output

Each IC is clocked. There is a wire between each block. The wire is updated each time slice. Instead of an RC network, the IC is clocked. In a monostable, the edge trigger could be a done using a delay and logic.

  input -- [ IC ] -- [ IC ] -- [ IC ] -- [ IC ] -- [ IC ] -- [ IC ] -- [ IC ] -- [ IC ] -- op => ip xor  button

  // Digital Monostable - trigger a count down that is ticked. A monostabled used a Resistor and Capacitor instead of an onClickTick().

  onInputEdge(){ 
    Set Count to 10 
  }
  onClockTick() { 
    decrement count down to zero , 
	if count == 5 set output 1 
	if count == 0 set output 0 
  }
  wire( a,b ){
   b.ip = a.op 
  }

Conclusion

Integrated circuits are connected together using bits of wire. Modelling this on a web page is an interesting diversion.

The simulated circuit was drawn https://www.circuit-diagram.org/editor/

This web page is based on a circuit like the one below, using D type Flip flops as delays. The web page models monostables use countdown state machines.
