2.3. Step 3: Preparing the Implementation Revisions for Debugging

To prepare the implementation revisions for debug, instantiate the SLD JTAG Bridge Host Intel® FPGA IP and the Intel Configuration Reset Release Endpoint to Debug Logic IP. Then, add a .stp file to the implementation revisions that you want to debug.

In this step, you prepare each of the revisions for debugging by repeating the preparation procedure for each of the following revisions:
  • blinking_led_slow
  • blinking_led_default
  • blinking_led_empty

To prepare the blinking_led_slow revision for debug:

  1. In the Intel® Quartus® Prime GUI, set blinking_led_slow as the current revision.
  2. Include sld_host.ip and config_reset_release_endpoint.ip as a project file in the blinking_led_slow implementation revision.

  3. In the file, update the port definition for the PR personas to include the required ports by uncommenting this block of code :
    //Uncomment this block to enable Signal Tap
    input wire reset,
    input wire tck,
    input wire tms,
    input wire tdi,
    input wire vir_tdi,
    input wire ena,
    output wire tdo,
  4. In the file, instantiate the sld_host IP in this persona by uncommenting the following block of code:
    // Uncomment this block to enable Signal Tap
    sld_host u_sld_hostled_two_on (
        .tck	(tck),     //   input,  width = 1, connect_to_bridge_host.tck
        .tms	(tms),     //   input,  width = 1,                       .tms
        .tdi	(tdi),     //   input,  width = 1,                       .tdi
        .vir_tdi (vir_tdi), //   input,  width = 1,                   .vir_tdi
        .ena	(ena),     //   input,  width = 1,                       .ena
        .tdo	(tdo)      //  output,  width = 1,                       .tdo
  5. In the the file, instantiate the config_reset_release_endpoint IP in this persona by uncommenting the following block of code:
    //Uncomment this block to enable Signal Tap
    config_reset_release_endpoint u_config_reset_release_endpoint (
        .conf_reset (reset)  //   input,  width = 1, conf_reset_in.reset
  6. Click Tools > Signal Tap Logic Analyzer to open the Signal Tap Logic Analyzer Window.

    If you are prompted to choose a template, select the Default template and click Create.

  7. Click File > Save As, and save the file as stp_slow.stp.

    You might get a message saying Input "Data and Trigger" is empty. Click OK to dismiss the message.

    A dialog box appears prompting you to enable Signal Tap file stp_slow.stp for the current project
    Figure 18. Enable stp_slow.stp for the Current Project
  8. Click Yes.
Repeat this procedure for the remaining revisions. Change the name of the Signal Tap file to correspond to the revision name as follows:
Revision Signal Tap File Name
blinking_led_default stp_default.stp
blinking_led_empty stp_empty.stp

You can disable Signal Tap in the project by clicking Assignments > Settings. In the Category pane select Signal Tap Logic Analyzer. Then, turn off Enable Signal Tap Logic Analyzer.
