Critical Issue
If you use the MegaWizard Plug-In Manager or the qmegawiz command
line utility to generate two instances of a 40- and 100-Gbps Ethernet
MAC and PHY IP core, one of them RX-only and one of them TX-only,
and then combine the two instances in the same design, the resulting
design cannot simulate. This issue occurs because simulation files
in the two instances have the same names.
To avoid this issue, generate your IP core instances using
the ip-generate command line utility, instead of the
MegaCore Plug-In Manager or the qmegawiz command line utility.
The following paragraphs provide basic information to help you formulate your ip-generate commands.
The ip-generate command to generate an instance
of the 40- and 100-Gbps Ethernet MAC and PHY IP core has the following
IP core-specific parameters:
| Component Parameter | Values |
DEVICE_FAMILY | “STRATIX IV”, “STRATIX V” |
MAC_CONFIG | “40Gbe”, “100Gbe” |
PHY_CONFIG | For MAC_CONFIG=”40Gbe”: 1 means the
regular 40GbE IP core, 2 means the 24.24 Gbps setting.
For MAC_CONFIG=”100Gbe”: 1 means the regular
100GbE IP core, 2 means the CAUI-4 setting. |
INTERFACE | “Custom-ST Interface”, “Avalon-ST
Interface” |
CORE_OPTION | “MAC only”, “PHY only”“MAC
& PHY” |
VARIANT | 1 means RX only, 2 means TX only, and 3 means duplex mode. |
Additional syntax details, including the command-line options for the different parameters, are provided by example.
For example, the following command generates a TX-only 40GbE MAC and PHY IP core instance that targets a Stratix IV device in a Stratix IV project and has a custom-ST interface:
ip-generate --output-dir=alt_e40_custom_tx_siv --file-set=SIM_VERILOG --output-name=alt_e40_custom_tx_siv
--report-file=txt:alt_e40_custom_tx_siv_ipd_report.txt --report-file=qip:alt_e40_custom_tx_siv/alt_e40_custom_tx_siv.qip
--report-file=csv:alt_e40_custom_tx_siv/alt_e40_custom_tx_siv.csv
--component-file=<Quartus II installation directory>/ip/altera/alt_eth_40g_100g/alt_e40_e100/alt_e40_e100_hw.tcl
--system-info=DEVICE_FAMILY=”Stratix IV” --component-param=MAC_CONFIG=”40
Gbe” --component-param=PHY_CONFIG=1 --component-param=INTERFACE=”Custom-ST Interface”
--component-param=DEVICE_FAMILY=”Stratix IV” --component-param=CORE_OPTION=”MAC
& PHY” --component-param=VARIANT=2
This issue will be fixed in a future version of the 40- and 100-Gbps Ethernet MAC and PHY IP core.
