What's Good About AMS Data Precision Options? They’re in the 16.6 Release!

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!
