5.1.2. PMA/FEC Direct PHY Multirate Hardware Design Example
Figue 34. PMA/FEC Diect PHY Multiate Hadwae Desig Example Block Diagam: 50G-1 Base Vaiat
Figue 35. PMA/FEC Diect PHY Multiate Hadwae Desig Example Block Diagam: 400G-8 Base Vaiat
I the hadwae desig example, the ISSP modules cotol the DUT IP eset sigals, d_mode selectio ad shows the status sigals. The hadwae test scipts ope sevice to the ISSP to ead ad dive the values. A JTAG host is istatiated to access the Avalo® memoy-mapped iteface.
The hadwae desig example executes the dyamic ecofiguatio tasitio pocess based o use selectio as stated i sc/paamete.tcl file ad checks the DUT IP status. Thee is a default dyamic ecofiguatio tasitio sequece, but use ca always modify the DR_TRANSITION aay vaiable i sc/paamete.tcl file.
DR_TRANSITION: Iteded DR sequece aay, size of this aay vaiable detemies the umbe of dyamic ecofiguatio to be pefomed.
- Fo example, if you wat to achieve the followig dyamic ecofiguatio sequece fo 50G-1 Base Vaiat: 1x50G > 1x25G > 1x50G KPFEC > 1x24.33024G > 1x50G, the vaiables chages ae:
set DR_TRANSITION(0) "1x25G" set DR_TRANSITION(1) "1x50G KPFEC" set DR_TRANSITION(2) "1x24.33024G" set DR_TRANSITION(3) "1x50G
- If you wat to achieve the followig dyamic ecofiguatio sequece fo 400G-8 Base Vaiat: 1x400G-8 > 2x100G-4 > 2x200G-4 > 1x400G-8G, the vaiables chages ae:
The vaiables chages ae: set DR_TRANSITION(0) "2x100G_4" set DR_TRANSITION(1) "2x200G_4" set DR_TRANSITION(2) "1x400G_8"
Hadwae Flow fo Desig Example:
The hadwae test desig <desig_example_di>/hadwae_test_desig/ diectoy cotais a hwtest subdiectoy that cotais .tcl scipt fo dyamic ecofiguatio hadwae testig. Follow the steps show below to test the desig example i hadwae.
Figue 36. Hadwae Flow fo PMA/FEC Diect PHY Multiate Hadwae Desig Example
The PMA/FEC Diect Multiate PHY Desig Example us the exteal loopback test by default with the loopback_mode paamete set to 0. Befoe pefomig ay hadwae test, attach the QSFP-DD loopback module accodig to the QSF piout assigmets of the espective desig example.
To pefom a iteal loopback test i hadwae, modify the loopback_mode paamete to 1 i the paamete.tcl file located i <desig_example_di>/hadwae_test_desig/hwtest/sc. Afte you compile the F-Tile dyamic ecofiguatio desig example ad cofigue it o you Agilex™ 7 device, you ca use the System Cosole to pogam the IP coe ad its PHY IP coe egistes.
About this task:
To stat the System Cosole ad test the hadwae desig example, follow these steps:
- Afte the hadwae desig example is cofigued o the Agilex™ 7 device, i the Itel Quatus Pime Po Editio softwae, click .
- I the Tcl Cosole pae, type cd hwtest to chage diectoy to <desig_example_di>/hadwae_test_desig/hwtest.
- Type souce mai_scipt.tcl to ope a coectio to the JTAG maste ad stat the test.
- Aalyze the esults. Successful u displays Test Passed i the System Cosole.
Note: If iteal seial loopback (ILB) is eabled fo the cuet pofile, you eed to disable it usig the FGT attibute access method befoe pefomig dyamic ecofiguatio to the ext taget pofile. If you do ot follow this, you might obseve that the Quatus Had IP pefoms abomally afte dyamic ecofiguatio.
