CWNANO finding timestamp of target codeblock execution between trigger_high() and trigger_low()

Given a c code, there are many instructions being executed between trigger_high() and trigger_low(). Corresponding hex code is burnt on cwnano chip. My attack will traget specific code block of the c code. Now, from python interface, how can I find the timestamp of that specific target code block between trigger_high() and trigger_low()? Or, may be how to capture power traces for that specific code block execution?


Unfortunately, the CWNano doesn’t have the ability to tell you how long the trigger was high for, so you’ll need to make a reasonable guess based on what the power trace looks like. The start of the power trace will correspond to the trigger_high() call.


Thank you @Alex_Dewar for the information.
