GENERAL DESCRIPTION: After installing the Express portion of the Foundation F1.5i Service Pack 1 with the default options set, you will see that you now have a Synopsys program group. Attempting to start the standalone FPGA Express GUI from this program group may lead to this message:
Cannot checkout an appropriate license for FPGA Express!
Clicking on OK leads to the following message:
ERROR STRING: Cannot find license file (-1,73:2) No such file or directory.
解决方案
Rather than using the LM_LICENSE_FILE variable, as is the case with Foundation Express, this particular executable will look for the license only in C:\FlexLM. Placing your license.dat in this directory will allow you to launch the FPGA Express GUI from this program group.
The Foundation Express icon within Xilinx Foundation Series -> Accessories is unaffected by the upgrade to Express 3.1.
