Dear Gentlemen; I am carrying out a study on the tool asimut of the system Alliance. Thanks to your collaboration and to my own investigations, I have been able to advance in my study. Now it arises me a new problem, I see that in the execution of a figure VHDL with the function " vhx_execute ", differs between elements bdd or gex (according to the transformations carried out in the process of compilation of the figure). I have found information it has more than enough bdd, but I don't find anything in your manuals on that they are the transformations gex. I would like that you told me that it means gex and where I can locate information on it. Thank you for their collaboration, sincerely Igor Cortés
