The PiL Transform is a hardware interface Transform that utilizes the Lauterbach Trace32 debugging software for both chip emulation and processor in the loop testing.  The Transform is meant to run as a bare metal system (that is, an initialization phase followed by an infinite loop that does the work phase).  The Transform operates through the debugger interface to provide a lock-step transmit/receive cycle.  This means that the Transform can operate in both real-time and accelerated-time modes without requiring a time delay in the Transform itself or in other Transforms downstream from the device.

You can use the PIL Transform for Back to Back (B2B) testing of Simulink models and target code running on a Lauterbach TRACE32 in-circuit emulator (ICE) or on an in-circuit debugger (ICD).

Back to back testing is used to demonstrate equivalence between a model and its generated C code. A requirement for ISO 26262 compliance states that test platform should “correspond as closely as possible to the target environment.” Another is for MC/DC level code coverage measurement. The optimum solution for Simulink model-based development is Lauterbach's ICE and Danlaw's RapiCover, coupled with MxSuite’s powerful test platform. By reusing test cases between MIL (Simulink) and PIL (Lauterbach) the need to qualify the code generator can be eliminated.

The PiL Transform performs processor-in-loop tests by establishing communication with T32, which runs target code. The Target code runs on a T32 either in Simulator or on hardware in which power debug interface has been used as debugger. The Power Debug Interface is connected to hardware via a JTAG Connector.

4.Send the HostId (labeled as 2 in the picture above) to rlmhostid-support@lauterbach.com or Rudolf.Dienstbeck@Lauterbach.com to request the license file.

1.Download and Install Trace32 software. Use the download link received from the Lauterbach team. If you didn’t receive a link, use this:

http://www.lauterbach.com/download_trace32.html

Note: At installation select (check) ARM X32 CPU family.

2.Download http://www.lauterbach.com/faq/lauterbach-cert-rlm9.zip

 This contains the lauterbach.set file you need.

3.Copy the received license file (.lic) and the Lauterbach.set file into the rlm installation directory. For example:

 C:\Reprise\rlm.v12.2BL2-x64_w3.admin\

4.Run rlm.exe. Ensure that it starts without any issues as shown here:

The S32 Design Studio IDE is a complimentary integrated development environment for Automotive and Ultra-Reliable Arm based MCUs that enables editing, compiling and debugging of designs. It is required for all sample projects.

1.Register and download here (it’s free):

https://www.nxp.com/support/developer-resources/run-time-software/s32-design-studio-ide/s32-design-studio-ide-for-arm-based-mcus:S32DS-ARM

2.Install S32-Design Studio. (At installation, use the Activation Code e-mailed to you by NXP.)

•Do not select Additional Items

•If you did not receive your Activation Code, it is available from the NXP website: Account>Software Licensing and Support>License Keys tab.
