Q2. How many overheads by the test point insertion are there?

A. It changes in the connection method with DynamicTracer.
Asynchronization bus connection
It depends at the wait cycle etc. of FlashROM.
As the reference value, it is one microsecond or less.
GPIO (4bit parallel) connection
It depends on the clock of the microcomputer.
It is 32bit microcomputer clock 144MHz about 3.3 microseconds/test point.
SPI connection
It depends on the clock of the microcomputer.
It is 32bit microcomputer clock 144MHz about 15 microseconds/test point.
It is 16bit microcomputer clock 20MHz about 50 microseconds/test point.
