After installation, users should verify the integrity of the software by checking the device info within the application. XGPro V11.90 includes a robust database that allows users to search for specific chip models. One of the "best" features of this version is the built-in logic gate tester and the ability to perform "in-circuit serial programming" (ICSP). This allows for flashing chips without desoldering them from the circuit board, provided the hardware setup supports it.
