General Description: The Demo/evaluation license that comes with F1.4 is only documented as limiting 2 features - target device size to base and no bitstream generation. However, the demo license also does not allow the use of the Constraints GUI in FPGA Express v2.0. Although BASE packages do not allow use of the Constraints GUI, the documentation is not clear that the tools are limited to BASE package features.
解决方案
Customers must request a regular license from Customer Service (800-624-4782) to access the Constraints GUI.
Note that a customer with a BASE package, even with a regular license, will not have access to the Constraints GUI. It is not part of the package.
