Description: When trying to access HDE Editor in Foundation, a blue message will show up in the Foundation project manager.
"HDE: Foundation option in Xilinx, keylock not found, VHDL not available".
After the HDL editor is opened, all the options for VHDL synthesis are grayed out. The key is plugged in the parallel port.
This may be caused by the Sentinel driver not being installed.
In the Project Manager, go to HELP->ABOUT PROJECT MANAGER, and check and see what's written after Keylock NO. If it says Keyless (for F1.3 only), it means that the Sentinel driver is not installed properly. For F1.4, the Keylock NO. should always be keyless.
The i386(Sentinel) driver can be installed from <path_to_active>\DRIVERS\WIN_NT or <path_to_active>\DRIVERS\WIN_95
[where <path_to_active> is by default C:\ACTIVE (F1.3) or C:\FNDTN\ACTIVE (F1.4)]
Double click on SETUPX86.exe (NT) or SENTW95.EXE (95). If the DRIVERS directory is not there for some reason. It can be found on the Foundation Design Entry tools CD in the ACTIVE directory. When the Sentinel Driver Setup Program window comes up, select Functions->Install Sentinel Driver.
In Win NT, the proper installation of the driver can be verified by going to the Control Panels -> Devices. Find the Sentinel driver and verify the it is 'Started'. If it is not, start the driver. It may be necessary to reboot after starting the driver. In Win 95, if you are unsure, it is best to just install the driver (no direct way to verify that it is running). This will not cause any problems. It may be necessary to reboot the machine.
Remove any other keys (ie parallel cable)or cables attached to the parallel port, allowing the Xilinx key to be the only one.
