Unfortunately the xes binary no longer functions with recent releases of the GNU C library. This page presents a possible solution that does not require any recompilation which would otherwise be ideal if the source code were available.
Either, simply replace the libtk8. This style sheet enables a2ps to pretty print Esterel programs, it is based on version 5. Fixing Esterel v5. The problem Running xes results in errors: Linking Acquire a libc. A States coverage scenario is converted into an ESI format, then the test-bench generator focuses on translating it into an equivalent scenario written in a target language such as VHDL, Verilog, The user design specified in one of those HDL languages could be compared with the same stimuli as the ones applyed to the 'golden model'.
The second interesting point in test generation concerns the multiple proposition of target languages. Designers are no longer restricted to any target language.
Target languages are relegated to middleware, the user need only be concerned about the ESI scenario file and ESO log files. The former is more flexible since most of the options are available. The latter is easier to use because little is required of the user bar clicking on an icon on the screen and perhaps the occasional parameter adjustment via the user settings panel.
The application is a stand-alone product, that is it can be executed alone without all of the ES environement. It is targetted at many different OS architectures such as Sun, Sparc, Windows, Irix and Linux, the application being separately compiled for each one. The user manual covers this aspect exhaustively.
The simplest way to use the Test-bench generator is without question through ES environement. Options settings are restricted, however, but an advanced options entry allows experienced user a means of feeding the application with those options.
We will now explain how to use the Test-bench generator. Firstly we will present the synopsis, and after that an overview of the ideal method to generate a test-bench. Here, the application synopsis takes an esterel file, an ESI scenario file and a esterel toplevel module as mandatory inputs.
Several options detailed in user manual are applyed on the generator to modify its behavior and generate an output scenario file. Selecting a target language, the application basically transforms the same stimuli as those found in the ESI file into the aforementionned language.
At compile time lexical and syntaxical errors in the inputs scenarii cause the application to crash, producing messages. Finally, a few user files are required to define user procedures, functions and data types in order to compile each target language.
To turn an user designed esterel model into a runnable application, we must begin by compiling the esterel files into a target language. Of course the module that originates from the ES compilation process has to be compatible with the ESI scenario compiled target language. At this stage we have compiled an esterel file and an esi scenario file into a specific target language.
Hence, we are now able to link them together in order to obtain an executable file. At run time, this application will generate a trace log file in ESO format. For example if in an ESI file an input A is emitted and according to the 'golden model' an output O is awaited, then the ESO log file contains A followed by the reaction function call and a comment: O. According to the user design, O may not be emitted by its own FSM, then this mismatch ensures that the hand-written model fails and must be reviewed.
We have observed how to use the application and how trivial it can be to compare log files with expected emitted outputs. We will overview the application of such generated test-benches to the validation processes.
A user could run several hand written tests as automatic scripts uppon a base. Generated ESO files are at run time generated for future tests purpose. The esterel design is mapped into a selected language, and with the state coverage option set, the user is ensured that all states will be visited. The inputs stimuli is recorded to a file in ESI format. As a by-product of this process, a test-bench will be generated from this states coverage scenario into the same selected target language.
At compile time on a target architecture, ESO file will log all statements and will contain the outputs. Consider how difficult it could be to collect all these outputs signals and make them match with ones produced by a 'golden model'. NB: Don't forget to indicate where, on the IP subnetwork e.

Plug-in is the primary means of executing script files directly from Esterel Studio. Predefined plug-ins are automatically available when you install Esterel Studio for the first time. This is not the case for updates and manual installation must be performed. Two ways are described in the following paragraphs.
Do the following actions to add the plug-ins lines in your existing plugin. The use of Esterel Studio software is governed by the conditions defined on delivery of the license agreement.
