Code coverage method for embedded system on chip

A code coverage method for an embedded System on Chip (SoC), comprising:

• adding, by a code coverage system of the SoC, a hook function at an entry and exit of each function of target source code that is compiled with an instrumentation option;
• and
• recording, by the code coverage system, at least one property of an instrumented function based on the hook function in a bit array in a memory of the SoC.

An apparatus for executing a code coverage method in an embedded System on Chip (SoC), comprising:

• a memory;
• and
• a processor including a code coverage engine configured to detect a presence of a utility function in target source code, add a hook function to the target source code, and record at least one property of the utility function based on the hook function in a bit array in the memory.
