I haven't been able to see a Hysteresis plot by using the DC Hysteresis sweep option. I have also enabled the 'DC operating point' option as well. I was expecting to find a negative going plot as well for the device but there is only a single Voltage transfer characteristic curve.
Following are the settings the Cadence spectre.out shows.
Important parameter values: reltol = 1e-03 abstol(V) = 1 uV abstol(I) = 1 pA temp = 120 C tnom = 27 C tempeffects = all gmindc = 1 pS hysteresis = on
Which verifies that hysteresis option is "ON". I am using MMSIM 11.1 and Cadence 6.1.5. Could you indicate where I could be going wrong?
No idea - this should work. Please contact customer support.
maybe you can check you DC sweep step size and use small linear step size (this may takes more time).
if you chose automatic and sweep within a wide range, the step size may be too large for spectre to give you accurate result( especially your hysteresis is small ).
hope that helps.thanks
