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.
