h1. Getting Started with MicroTESK: demo of x86 {{toc}} h2. Prerequisite Install MicroTESK (for more information see [[Installation_Guide]]) http://forge.ispras.ru/projects/microtesk/wiki/Installation_Guide) h2. Overview of the x86 ISA Specifications of x86 can be found into @$MICROTESK_HOME/arch/demo/x86/model@. Each instruction is described by means of the following constructs (register move instruction is taken as an example) ## Its declaration <pre>op mov_r1616 (dst: GPR16, src: GPR16)</pre> ## Its assembly representation <pre>syntax = format("mov %s, %s", dst.syntax, src.syntax)</pre> ## Its binary coding <pre>image = format("1000101111%s%s", dst.image, src.image)</pre> ## Its semantics <pre> action = { dst = src; instr_size = instr_size + 2; } </pre> To run the model, use the following command: <pre>$MICROTESK_HOME/bin/compile.sh x86.nml</pre> For more information, see MicroTESK wiki: http://forge.ispras.ru/projects/microtesk/wiki/NML_Language_Reference h2. Overview of x86 Test Templates Test templates for the x86 model can be found into @$MICROTESK_HOME/arch/demo/x86/templates@. As by now, it contains six demonstration templates: # @block.rb@ to show usage of the instruction blocks # @block_random.rb@ to show creation of the randomized instruction sequences using block constructs # @euclid.rb@ to show MicroTESK simulating the execution of a test program to predict the resulting state of the PE under test # @random.rb@ to show generation of the randomized test cases by using biased values, intervals, arrays and distributions # @random_immediate.rb@ to show generation of random immediate values # @random_registers.rb@ to show dependent instructions with random registers To run template processing use the following command: <pre>$MICROTESK_HOME/bin/generate.sh x86 block.rb --code-file-prefix block --code-file-extension -v</pre> When the processing is finished, files with the resulting assembly code can be found in @$MICROTESK_HOME@ For more information, see MicroTESK wiki: http://forge.ispras.ru/projects/microtesk/wiki/Template_Description_Language
