MicroTESK » MicroTESK for ARM Demo

h2. ISA

The [[Instruction Set Architecture]] of MicroTESK for ARM Demo version.

h2. Installation Steps

# "Download":https://forge.ispras.ru/projects/microtesk-arm-demo/files and unpack a distribution package (the latest @.tar.gz@ file).

  The destination directory will be further referred to as @<INSTALL_DIR>@.

# Set the @MICROTESK_HOME@ environment variable to the @<INSTALL_DIR>@ path (see "Setting Environment Variables":https://forge.ispras.ru/projects/microtesk/wiki/Installation_Guide#Setting-Environment-Variables).

# Add the @<INSTALL_DIR>/bin@ path to the @PATH@ environment variable.

# If required, install SMT solver(s) to the @<INSTALL_DIR>/tools@ directory (see "Installing SMT Solvers":https://forge.ispras.ru/projects/microtesk/wiki/Installation_Guide#Installing-SMT-Solvers).

You can learn more about "Installation Directory Structure":https://forge.ispras.ru/projects/microtesk/wiki/Installation_Guide#Installation-Directory-Structure by following the link.

Next we will use the following directories:

* arch - contains microprocessor specifications and test templates.

* bin - contains scripts for model compilation and test generation

h2. Test Program Generation

To generate the test program for the ARM architecture (model) and the @bubble_sort@ template, run the following command:

<pre>

$ cd $MICROTESK_HOME

$ sh bin/generate.sh armv8 arch/armv8/templates/bubble_sort.rb -dgp memory

</pre>

The output file name depends on the @--code-file-prefix@ and @--code-file-extension@ options (see "Command-Line Options":https://forge.ispras.ru/projects/microtesk/wiki/Command-Line_Options).

h3. Self-Check Test Program Generation

To generate the self-check test program for the the @bubble_sort@ template, run the following command:

<pre>

$ sh bin/generate.sh armv8 arch/armv8/templates/bubble_sort.rb -dgp memory -sc

</pre>

h3. Templates

The entire list of demo templates can be found in the directory: @<INSTALL_DIR>/arch/armv8/templates@.

<pre>

$ cd $MICROTESK_HOME/arch/armv8/templates

</pre>

You can use the @run.sh@ script from this directory to generate the test program:

<pre>

./run.sh branch_generation

</pre>

The generated test program will be in this directory: @$MICROTESK_HOME/output_test/branch_generation@

<pre>

cd $MICROTESK_HOME/output_test/branch_generation

</pre>

Also you can use the @run-sc.sh@ script from this directory to generate the *self-check* test program:

<pre>

./run.sh branch_generation

</pre>

The generated test program will be in this directory: @$MICROTESK_HOME/output_test_sc/branch_generation@

h3. Test trace

The option @--tracer-log@ enables generation of tracer logs for simulation. (In scripts @run.sh@, @run-sc.sh@ it is enabled.)

The trace format is described here: https://forge.ispras.ru/projects/qemu4v/wiki/QEMU4V_Trace_Format

The test trace you can compare with the program execution trace on simulator. You can use the "Trace Matcher":https://forge.ispras.ru/projects/traceutils/wiki tool.

To simulate ARMv8 assembler programs you can use "QEMU4V":https://forge.ispras.ru/projects/qemu4v/wiki/Installation tool.

Or you can use the approach shown in the picture below:
