  • Re: PSpice A/D accuracy in V16.3?
    I did the same simulations with LTspice (V4.11) setting the option NUMDGT = 6 and 7. In the first case I get the same result as with PSpice --> single precision. With NUMDGT = 7, LTSpice switches his output to double precision. Thanks for your answer!

  • PSpice A/D accuracy in V16.3?
     Did some simulation with high dynamic range (using a SUM ABM Model : adding a constant value of 1 with a sinus-wave having 120nV as amplitude) . I was supprized getting quantized data with a LSB of 60nV which corresponds to single precision (mantissa hase 23 + 1Bits). Is there any chance to get double precision? Here my sim settings: ...
