Hallo Alex,
ich benutze die freie Version von Modelsim (Xilinx Version).
Hast Du bei Xilinx ein Lizenzdatei angefordert? Die Lizenz ist
an den Rechner auf dem Du es installiert gebunden.
Von der Xilinx homepage:
"
Obtaining a License for the Starter Version of MXE
Although MXE Starter is free, it still requires a license.
Towards the end of the installation, you are asked if you want to
license the product over the Web. If you answer "Yes", a browser
window containing the ModelSim XE license request page opens.
If you answer "No", you have the option to license the product at the
ModelSim XE license site by selecting:
Start ->Programs ->ModelSim XE ->Submit License Request
The license is locked to the "C" drive disk ID. If you change the
"C" drive disk ID or install MXE Starter on another machine, you must
obtain a new license.
The license request page for the Starter Version of MXE does not
require a serial number. If the license request page asks for a serial
number, please see (Xilinx Answer 17070). "
