Introduction to C-SPY®

hardware debugger

systems

This chapter introduces you to the C-SPY drivers and to how they differ from

the C-SPY Simulator.

The C-SPY emulator drivers

C-SPY consists of both a general part which provides a basic set of C-SPY features, and

a driver. The C-SPY driver is the part that provides communication with and control of

the target system. The driver also provides a user interface—special menus, windows,

and dialog boxes—to the functions provided by the target system, for instance special

breakpoints. This driver is automatically installed during the installation of IAR

Embedded Workbench.

This guide describes the operation of the IAR C-SPY drivers for the following Renesas

hardware debugger systems:

● E8/E8a Emulator

● E10A-USB Emulator.

For further details about the concepts that are related to C-SPY, see information about

the general debugger features, see the IAR Embedded Workbench® IDE User Guide.
