Parallel wells scale chip heat while cycle count also scales elapsed time. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Four wells share one four-cycle schedule
Per-step heat is 100 joules. With 4 cycles and 4 wells, chip heat is 4800 joules while elapsed time is 120 seconds.
100⋅3⋅4⋅4=4800
Doubling wells doubles heat but not elapsed time
The same 4 cycles with 8 wells make chip heat 9600 joules, still on a 120 second schedule.
100⋅3⋅4⋅8=9600
Adding cycles raises both heat and elapsed time
6 cycles with 8 wells make chip heat 14400 joules and elapsed time 180 seconds.
