New to OK- Unable to Translate First.v

Spartan-3 USB 2.0 Modules
1

Hello,

I get errors translating a “First” design. The error report is listed below.

I created a new project, added First.v from the example file, its UCF file along with okLibrary.v. The synthesis completes successfully.

Can you help? I am new to Opal Kelly and haven’t done FPGA design in over a year. Is there a setup issue?

Thanks,

Checking expanded design …

It looks like you forgot to include the NGC files. You’ll need to place these in your build directory.

Thanks,

For organizational purposes, I had placed all .ngc files in a “okLibrary” folder which resided under the main project folder. I moved all files (.ngc, .vhdl and .v) out of “okLibrary” folder and placed them under “First” and translating design completes successfully.

For completeness,

Project folder: C:\xilinx_projects\First
okLibrary folder: C:\xilinx_projects\TestOpalKelly\okLibrary <= INCORRECT!!!

Yes, that’s right. Unless you direct MAP to the directory (it’s an option in ISE), it will not know where to look, so it only searches the project directory.
