vary the value of a pulse or clock source

[mdmartin]

I have a heartbeat signal (an alarm) that pulses between 0 V and 3.3 V every 250 usec. However, the 3.3 V can be as low as 2.4 V. I'm designing a circuit that will translate this into a pulsing signal with more reliable voltage levels (say 0 V to 3 V). My problem is how can I vary the maximum value of a pulse (or clock or more appropriate source) between 2.4 V and 3.3 V within a simulation, i.e. without having to run multiple times and changing the value after each run?

Regards,

Martin

Hi Martin, 

The easiest way to do what you are describing is to place multiple clocks, set the voltage/frequency for each clock to the level you need and then tide them to a switch. While simulating you can toggle the switch and this should give you different signals without stop/start the simulation.
