  • Page 5: Introduction

    Readers This manual is intended for users who wish to perform debugging using the QB-V850E2 (generic name: IECUBE2). The readers of this manual are assumed to be familiar with the device functions and usage, and to have knowledge of debuggers.
  • Page 6 This is the system to be debugged (system provided by the user). This includes the target program and the hardware provided by the user. ® IECUBE Generic name for NEC Electronics’ high-performance, compact in-circuit emulator. This is IECUBE2 peripheral to interface with the target system.

  • Page 7: Chapter 1 General

    The IECUBE2 is an in-circuit emulator for V850E2M microcontroller. Hardware and software can be debugged efficiently in the development of systems in which the target device is used. This manual describes general information of IECUBE2 main unit. Please refer to user’s manual of each POD for detail usage.

  • Page 8: Hardware Specifications

    2.25G Byte (Approx. 128M frame ) (When using long term trace option) System Overview The system configuration is described as below. IECUBE2 can not be used alone. POD, AC adapter and sockets are needed to use. These are sold separately.

  • Page 9: Functional Overview

    9/19 Functional Overview IECUBE2 is provided with a wealth of debug functions to enable efficient program debugging, in addition to being used to emulate the operation of a target device. An overview of the functions is provided in this section.
  • Page 10 User’s Manual（Preliminary） IECUBE2 main (QB-V850E2) ZUD-CD-10-0092 10/19 (1) Hardware break function The hardware break function is used to observe the CPU bus cycles and set a break for a specific fetch or access operation. For example, a break can be set by detecting a state where an address has been executed or a variable has been accessed.

    User’s Manual（Preliminary） IECUBE2 main (QB-V850E2) ZUD-CD-10-0092 11/19 1.3.4 Trace function (program execution history) The trace function can be used to check the CPU execution history (trace). Items (1) to (7) can be recorded in the execution history. (1) Program counter (PC) of branch source and branch destination The PCs of a branch source and a branch destination can be recorded in the history.

  • Page 12: Time Measurement Function

    User’s Manual（Preliminary） IECUBE2 main (QB-V850E2) ZUD-CD-10-0092 12/19 1.3.5 Time measurement function This function is used to measure the execution time of a specific section. The measurement start and end points can be set by using the event function. In addition, the maximum, minimum, and average execution time and the number by which the measurement section has been passed can be measured.

  • Page 13: Event Link Function (Event Combinations)

    User’s Manual（Preliminary） IECUBE2 main (QB-V850E2) ZUD-CD-10-0092 13/19 1.3.7 Event link function (event combinations) The event link function is used to combine into one event, events that have been registered by using the event function. It is used to detect a specific sequence, such as when an address has been executed after a variable was accessed.

  • Page 14: Ac Adaptor

    14/19 AC adaptor The specifications of the AC adapter for IECUBE2 differ depending on the region of use. Be sure to use an AC adapter corresponding to the region of use. The IECUBE2 is not provided with an AC adapter. It must be purchased separately.

    User’s Manual（Preliminary） IECUBE2 main (QB-V850E2) ZUD-CD-10-0092 17/19 Stick for unplugging EA from POD The stick as following figure is used to unplug Exchange Adapter (EA) from POD. Figure 2-2. Stick for unplugging EA from POD To unplug EA from POD, insert the stick in a corner of POD and slightly push up POD.

  • Page 18: Chapter 3 Notes

    A time stamp of trace function does not indicate the instruction execution time/cycle count. A time stamp indicates a time IECUBE2 main received the trace data from a debug chip in POD. The output timing of the trace data is a little different from the instruction execution time/cycle.

  • Page 19: Chapter 4 Long Term Trace Option

    LONG TERM TRACE OPTION This chapter explains an optional product QB-V850E2-SP for extending the trace memory. General The QB-V850E2-SP is a trace memory extension for IECUBE2. Please make sure the supported version of debugger software. Figure 4-1. QB-V850E2-SP SETUP PROCEDURE This section describes how to connect the QB-V850E2-SP to the IECUBE2 main.
