Missing SignalTap II Generation File in JESD204B IP Core Nios II Processor Control Unit Design Example

Description

The Nios II Processor Control Unit design example does not generate the required XML file in the debug STP directory (<example_design_directory>/ed_nios/jesd204b_ed_qsys/altera_jesd204_tx_mlpcs_160/synth/debug/stp). Both the TCL and XML files are required for SignalTap (STP) file generation but the debug STP directory contains only the build_stp.tcl file.

The RTL State Machine Control Unit design example and standalone JESD204B IP core generation are not impacted.

Resolution

Generate a standalone JESD204B IP core with the following parameter settings:

Wrapper Options: Both Base and Phy

Data Path: Duplex

The debug STP directory of the IP core you generate should include both the build_stp.tcl and jesd204b_base_phy_duplex.xml files.

You can also refer to the steps outlined in the JESD204B IP Core User Guide, "Creating a SignalTap II Debug File to Match Your Design Hierarchy" topic. When generating the STP file in the design example debug STP directory, point the XML file input switch -xml_file to your standalone JESD204B IP core debug STP directory (<ip_variant_name>/altera_jesd204_tx_mlpcs_160/synth/debug/stp/jesd204b_base_phy_duplex.xml).

This issue will be fixed in a future release.
