Hi,

Currently i am using Proteus 7.4SP3 to simulate the AD633 multiplier. The two input is a trend of pulses and i want to get the output. The problem is that it occur 2 warnings which is then stopped my simulation.

1. [SPICE] DELMIN increased to 1.11022e-016 due to lack of time precision
2. [SPICE] TRAN: Timestep too small; timestep = 0: trouble with node #v:u1:nc#branch

Please help and commend about the problem. I need your help very much. Thanks =)

    I think your both the errors are similar. You said your input is a trend of pulses. But the error says-" Timestep too small; timestep = 0"...which means that there is no time difference between the instants at which your input is sampled. Please try increasing the interval at which your simulator takes values from the input. Also if possible try the same program in MATLAB.
