Testing, Simulation and Debugging Techniques and Tools: Lesson-5 In-Circuit Emulator Chapter-15L05: "Embedded Systems- Architecture, Programming and Design", 2015 1 Raj Kamal, Publs.: McGraw-Hill Education 1. Development processes using ICE Chapter-15L05: "Embedded Systems- Architecture, Programming and Design", 2015 2 Raj Kamal, Publs.: McGraw-Hill Education Target debugging Simulation Use Use target emulator monitor Circuit for emulating target system remains independent of a particular targeted system and processor Chapter-15L05: "Embedded Systems- Architecture, Programming and Design", 2015 3 Raj Kamal, Publs.: McGraw-Hill Education Using an Emulator or ICE • A circuit for emulating target system remains independent of a particular targeted system and processor • Emulator or ICE provides great flexibility and ease for developing various applications on a single system in place of testing that multiple targeted systems. Chapter-15L05: "Embedded Systems- Architecture, Programming and Design", 2015 4 Raj Kamal, Publs.: McGraw-Hill Education An Emulator Chapter-15L05: "Embedded Systems- Architecture, Programming and Design", 2015 5 Raj Kamal, Publs.: McGraw-Hill Education An ICE Chapter-15L05: "Embedded Systems- Architecture, Programming and Design", 2015 6 Raj Kamal, Publs.: McGraw-Hill Education Emulator Emulates MCU inputs from sensors Emulates controlled outputs for the peripheral interfaces/systems Emulates target MCU IOs and socket to connect externally MCU Chapter-15L05: "Embedded Systems- Architecture, Programming and Design", 2015 7 Raj Kamal, Publs.: McGraw-Hill Education ICE • Means In-Circuit Emulator • Interface COM port of a computer • Emulates target MCU IOs • ICE socket connects MCU externally Chapter-15L05: "Embedded Systems- Architecture, Programming and Design", 2015 8 Raj Kamal, Publs.: McGraw-Hill Education ICE… • Uses computer developed object files and hex files for the MCU • Uses debugger at the computer developed files for the MCU application Chapter-15L05: "Embedded Systems- Architecture, Programming and Design", 2015 9 Raj Kamal, Publs.: McGraw-Hill Education A Emulator Chapter-15L05: "Embedded Systems- Architecture, Programming and Design", 2015 10 Raj Kamal, Publs.: McGraw-Hill Education Difference in Emulator and ICE • Emulator uses the circuit consisting of the microcontroller or processor itself. The emulator emulates the target system with extended memory and with codes downloading ability during the edit-test- debug cycles. Chapter-15L05: "Embedded Systems- Architecture, Programming and Design", 2015 11 Raj Kamal, Publs.: McGraw-Hill Education Emulator and ICE … • ROM Emulator emulates only a ROM. • ICE uses another circuit with a card that connects to target processor (or circuit) through a socket.
