Virtual JTAG Intel® FPGA IP Core User Guide

Configuring the JTAG User Code Setting

The following steps describe how to configure the JTAG User Code setting. A separate script generates the GUI and is executed with the quartus_stp command line executable. During runtime, the GUI queries the device for the version information and formats it for display within the message box.
  1. On the Assignment menu, click Settings.
  2. On the Settings page, in the Category list, click Device.
  3. The Device dialog box appears. Click Device and Pin Options.
  4. In the Device and Pin Options dialog box, on the General tab, the JTAG user code appears. Type the user code in 32-bit hexadecimal format.
  5. Click OK.
