It's the other way around, like the fast-attack/slow-release AGC in single sideband receivers. Except that Jim wants to reset it when keyed off.
I rarely have to use that in SPICE but stuff like this I mostly fudge out of real parts with the important values at the extremes, where the computer doesn't beep and the results are still reasonably accurate.
In SPICE one can simulate a deliciuous meal that has almost zero calories, no fat and will not add one gram of weight to your body. Then when you actually cook and eat it the cholesterol shoots way up.
That may or may not be PSpice specific. I thought about it some. Start with a "standard" track and hold, add a fast comparator to convert to a peak and hold (two if you want both peaks). Add some enable circuitry to handle any ADC converter setup and hold times and data transfer as needed.. Did something like this about 20 years ago for what was then Hughes EDSG. Location of the analog / digital boundary is engineer choice.

Took awhile. We had one of those "events" last night. Wife got an enormous nosebleed. Finally convinced her we needed to take her to an Urgent Care provider. Cauterization didn't work, so they inserted a balloon-like inflatable device (they called it a "rocket" :-) up her nose, and we went back 3.5 hours later and they removed it... bleeding stopped.
