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:
