What's Good About AMS Data Precision Options? They're in the 16.6 Release! Posted: 13 May 2013 09:14 AM PDT Just a brief blog today to introduce that 16.6 Allegro AMS Simulator (PSpice) now provides 64-bit data precision by default. This ensures a higher precision compared to the 32-bit data. For example, when a very small amplitude voltage is superimposed on a large voltage, the resulting voltage loses its resolution, displaying staircase waveforms. With 64-bit precision, for the same signal, a perfect ramp waveform is displayed. Here's a simulation output with the 32-bit data precision set (notice the staircase style of output):   Now, change the Probe Data option to 64-bit: Here's the resulting waveform (notice the smooth results): I look forward to your feedback!   Jerry "GenPart" Grzenia
