Triple Speed Ethernet IP Core Cyclone IV VHDL Customer Testbench Fail to Run

Environment

  • Intel® Quartus® Prime Pro Edition
  • Ethernet
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT

    Critical Issue

    Description

    The Triple Speed Ethernet (TSE) IP core VHDL customer testbench targeting Cyclone IV devices for the following settings may fail to run:

    Core variation: 10/100/1000Mb Ethernet MAC with 1000BASE-X/SGMII PCS

    Use internal FIFO: No

    Number of ports: 4

    Transceiver type: GXB

    Export transceiver powerdown signal: Yes

    Resolution

    Perform these steps to modify the testbench file:

    1. Open the top-level testbench file, <instance_name>_tb.vhd.

    2. Search for generate-block with the name "FourPort_DUT_without_FIFO".

    3. Add the following lines in the generate-block:

    gxb_pwrdn_in_0 <= gxb_pwrdn_in; gxb_pwrdn_in_1 <= gxb_pwrdn_in; gxb_pwrdn_in_2 <= gxb_pwrdn_in; gxb_pwrdn_in_3 <= gxb_pwrdn_in;

    This issue will be fixed in a future release.
