CAN-CN FPGA: PolarFire PCIe L2P2 Txuas Lub Xeev Txhawb
Microchip Corporation
Kawm Subject: CAN-CN FPGA: PolarFire PCI Express L2P2 txuas lub xeev kev txhawb nqa
Nqe lus piav qhia:
Hauv Libero SoC tso tawm 2022.1 qhov kev xaiv los pab kom L2P2 lub zog tswj kev txuas tau raug tshem tawm los ntawm Tsim SERDES Initialization GUI. Tag nrho PolarFire transceiver PCIe Link Training thiab Status State Machine (LTSSM) hardware blocks tsis txhawb L2P2 fais fab kev tswj txuas xeev.
Yog vim li cas rau kev hloov:
PolarFire transceiver blocks suav nrog embedded PCIe Gen1 thiab Gen2 Root-chaw nres nkoj thiab End-point controllers. PCIe Sub-system (PCIESS) LTSSM txhawb nqa Link Training states thiab Re-Training (Rov qab) xeev. Txawm li cas los xij, PCIESS tsis txhawb nqa ib qho software uas tau tsav lub zog tswj lub xeev xws li L2P2, raws li tau sau tseg tsis raug hauv cov ntaub ntawv qub.
- Software-tsav L2P2 nkag teb chaws cov lus txib tawm los ntawm PolarFire PCIESS hauv paus-Chaw nres nkoj mus rau cov ntsiab lus qis kawg tsis txaus siab. Raws li lub hauv paus-chaw nres nkoj, qhov no yuav ua rau qhov txuas kom cuam tshuam tag nrho thiab tsuas yog rov qab tau los ntawm kev rov pib qhov txuas nrog sab-band PERSTn (tseem ceeb pib dua) lossis lub voj voog hluav taws xob.
- PolarFire PCIESS End-point yuav tsum tsis txhob raug txib los ntawm tus tswv tsev kom nkag mus rau L2P2 txuas xeev. Raws li qhov kawg-point, qhov txuas yuav cuam tshuam thiab tsuas yog rov qab tau los ntawm kev rov pib qhov txuas nrog sab-band PERSTn (tseem ceeb pib dua) lossis lub voj voog hluav taws xob.
Daim ntawv thov cuam tshuam:
Cov khoom siv PolarFire tsis txhawb L2P2 lub zog tswj kev txuas hauv xeev.
- Txhawm rau kom tsis txhob cuam tshuam kev cuam tshuam, PCIe lub zog tswj software yuav tsum tsis txhob hais kom PolarFire PCIESS Root-chaw nres nkoj lossis End-point nkag mus rau lub xeev qis zog txuas (L2).
- Nws tsis ua tiav kev siv hluav taws xob txuag ntxiv rau PolarFire ntaus ntawv.
- Libero SoC tso tawm 2022.1 tau hloov kho los tshaj tawm cov neeg xiam D3hot thiab D3cold hauv PCI Txoj Cai Tswjfwm Ntiag Tug ntawm peb qhov chaw xaus Config
- Txhawm rau ua tiav kev txuag hluav taws xob ntxiv, nyob rau sab saum toj ntawm lub tshuab hluav taws xob tau zoo tshaj PolarFire, tus tsim FPGA yuav tsum ntiav cov tswv yim tswj fais fab ncaj qha rau FPGA ntaub tsim.
Yuav tsum ua:
- Cov neeg siv yuav tsum siv cov ntaub ntawv tshiab muab los ntawm Microchip hais txog PCIESS link Training State txhawb..

- Xa mus rau PolarFire FPGA Low Power Application Note rau cov cuab yeej nta uas cov neeg siv tuaj yeem ua haujlwm los tsim kev txuag hluav taws xob ntxiv rau hauv lawv cov qauv tsim.
