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