Result and discussion

This chapter will present and discuss the result of the thesis. First a section ex-

plaining how the concept of integrating data read from the target CPU by JTAG in

CANoe works in practice, followed by a section explaining how the software test of

the ECU works with this solution.

7.1 Concept

The data extracted from the target CPU via its JTAG interface is provided to CANoe

by a dll - created in Visual Studio 2010, written in C++ - using the CANoe and

Trace32 API:s loaded as a ’C-library’ in CANoe. To incorporate this solution in an

existing CANoe conﬁguration the user has to follow the work ﬂow below.

• Manually create a txt-ﬁle containing debug variables and dependencies, see

Figure 6.2.

• Create a ﬁle deﬁning what variables exist in which debug case, see Figure

2.7, named ”CANoeUserFileDebugCase.txt”.

• Use the graphical user application, see Section 6.2, in order to create the ﬁle

with the variables with associated address and size. Use default ﬁle name -

”CANoeUserFileDebugVars.txt”.

• Load the newly created ﬁle together with the debug case ﬁle in ’User Files’

in CANoe conﬁguration options.

• Load the dll in ’C-libraries’ in CANoe conﬁguration options.

• Add the system variables deﬁned in the ﬁrst ﬁle in the CANoe conﬁguration

under the namespace and the feedback system variables, see Section 6.4,

in a sub namespace to called .
