Anything related to LTspice. LTspice is a SPICE simulation, schematic capture, and waveform viewer program from Linear Technology. LTspice is freeware with a very liberal license, it is lightweight, and isn't crippled in any way.

LTspice error, EKG

Your capacitor values are incorrectly specified (you need to write 470p and 3.3u rather than 470 pf and 3.3 mu) The negative terminals of V1 and V2 aren't connected to anything.

Calculation in LTspice "never" finishes

I tried implementing the circuit from your application note in LTspice and it worked (it is here), but: I used the LT1720 since it was already in the LTspice libraries has a 4.5 ns propagation delay …

Is there any function for multiplying two voltage waveforms in LTspice?

You can use a 'bv' element, for example (the trace in pink is V(Va) * V(Vb)):

Digital simulation display

In LTspice you won't have any way to display data except for waveform plots - which is what you're going to use most of the time for analog circuit design. …
