MicroTESK

h1. Getting Started with the x86 Demo

{{toc}}

h2. Prerequisite

MicroTESK should be installed (see [[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>

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@
