Pcie Ts1 Ordered Set, TS0 has alternate bits set to 0, to enable its 本文详细介绍了PCIe物理层中的训练序列TS1和TS2的作用，它们在位对齐、符号对齐和参数交换中的功能。 TS1用于检测链路配置信息，TS2则确 Choice of Ordered Set encoding to be such that one can always correctly do block alignment Another challenge is bit slip initially, based on past observation Solution: Continuously do block alignment in The four different types of ordered sets are Training Sequence ordered sets (TS1s and TS2s), Electrical Idle ordered sets (EIOS), Skip ordered sets (SKP), and Fast Training Sequence ordered sets (FTS). Active , It is written in the spec: "The Transmitter sends out TS1 Ordered Sets with Link numbers and Lane numbers set to PAD on all the active Upstream Lanes; the inactive Lanes it is initiating to In phase 1, both ports exchange TS1 ordered sets, interspersing an Electrical Idle Exit Ordered Set (EIEOS) after every 32 TS1 ordered sets, to establish an operational link. 0 introduced a new type of Ordered set, TS0 which is analogous in functionality to that of TS1. 0 GT/s 时，Ordered Sets 永远不会被加扰，而是始终采用 8b/10b 编码。 当数据速率为 8. It configures the PHY and establishes the PCIe link by How PCIe establishes, trains, and synchronizes lanes before data transmission begins. The purpose of 前面的文章中提到過，Ordered Sets分別有以下幾種：TS1 and TS2 Ordered Set (TS1OS/TS2OS)、Electrical Idle Ordered Set (EIOS) As mentioned in the previous article, there are the following types of Ordered Sets: TS1 and TS2 Ordered Set (TS1OS/TS2OS), Electrical Idle Ordered As per PCIe 6. 文章详细阐述了物理层中的控制字符，如PAD用于数据流对齐的填充，有序集（包括TS1&TS2训练序列、SKP、EIOS、FTS和EIEOS）则涉及链 TS1 and TS2 Ordered Sets训练序列TS1和TS2是训练过程中最被关注的。 TS1和TS2由16个符号组成，它们在LTSSM训练状态机的轮询、配置和恢复状态进行 Sets and resets links and ports to allow packets to be sent. The DSP is responsible for Spec定义了如下有序集： TS1&TS2（Training Sequence ）训练序列1和2： 用于链路初始化、链路训练，协商链路的速率、宽度等。 SKP有序集： 1. 0 spec, the Loopback Follower device enters Loopback whenever two consecutive TS1 Ordered Sets are received with Fig 3 Verification and Simulation Results (a) Verification Environment (b) Simulation of detection of all Ordered Sets (c) Simulation result of FTS and TS1 Ordered Set 而不能出现一个Lane正在发送Ordered Set进行与链路训练相关的操作，而其他Lane进行其他数据传递的情况。 PCIe链路发送TLP与发 前面的文章中提到过，Ordered Sets分别有以下几种：TS1 and TS2 Ordered Set (TS1OS/TS2OS)、Electrical Idle Ordered Set Polling State 지금까지 링크는 Electrical Idle(전기적 유휴) 상태에 있었습니다. PCIe 6. 5 GT/s 或 5. (a) During Polling. TS0 has alternate bits set to Fig 3 Verification and Simulation Results (a) Verification Environment (b) Simulation of detection of all Ordered Sets (c) Simulation result of FTS and TS1 Ordered Set 2 有序集 – Ordered Sets Ordered Sets 用于两个设备物理层之间的通信。 Gen1/2 总是以字符 COM 开头。 用于链路训练，时钟补偿和改变链路功 Modified TS1/TS2 Ordered Sets are exchanged during Alternate Protocol negotiation with Modified TS Usage = 010b. 5GT or 5GT 它们不会被扰码 (scramble)， 经过Phase 0/1后，TS1 Order Set可以被正确接收，BER达到了<10^-4的要求； 如果认为Phase 0/1后，信号质量达到要求，可以不进行Phase 2/3的调节。 EQ Phase2: USP调 . I am not PCIe expert, but I want to share my understanding. What is Ordered Set?Link간의 communication은 Ordered Set을 통하여 이루어집니다. 文章详细阐述了物理层中的控制字符，如PAD用于数据流对齐的填充，有序集（包括TS1&TS2训练序列、SKP、EIOS、FTS和EIEOS）则涉及链路 今天这篇文章，主要汇总一下PCIe physical layer中链路训练（Link Training）的各种Sequence及Ordered Sets。 Training SequenceTraining Sequence主要用于bit alignment, Symbol PCIe gen 6 introduces a new ordered set TS0 with functionality similar to that of TS1, and changes the definition of TS1 and TS2 ordered sets to incorporate replication of data. 그러나 Polling 상태에서는 LTSSM TS1 및 TS2 解决方案是在训练有序集中包含更多的电气空闲退出有序集（ EIEOS,Electrical Idle Exit Ordered Set)，用于定位边界。 可以通过查找 00h 和 FFh 字节交替的数据图样来找到 Training Sequence是由Order Set (OS) 组成，它们主要是用于bit aligment，symbol aligment，交换物理层的参数。当data_rate = 2. 모든 Ordered Set은 K character (comma, COM라고도 표기)로 시작하고, 전송되는 Ordered Set에 前面的文章中提到过，Ordered Sets分别有以下几种：TS1 and TS2 Ordered Set (TS1OS/TS2OS)、Electrical Idle Ordered Set (EIOS)、FTS Ordered Set (FTSOS)、SKP Ordered 前面的文章中提到过，Ordered Sets分别有以下几种：TS1 and TS2 Ordered Set (TS1OS/TS2OS)、Electrical Idle Ordered Set (EIOS)、FTS Ordered Set (FTSOS)、SKP Ordered Ordered Set payload not scrambled except last 15 Symbols of TS1/ TS2 Degree 23 polynomial (G(X) = X23 + X21 + X16 + X8 + X5 + X2 + 1) Different taps for 8 adjacent lanes (or different You will not find detailed explanation on Xilinx document. Additionally, 训练序列由用于初始化位对齐（ initializing bit alignment）、符号对齐（Symbol alignmen）和交换物理层参数（ exchange Physical Layer parameters）的有序集组成。当数据速率为 2. 0 GT/s 或更高时，使用 128b/130b 编码，需要对其进行加扰。 在进行建链的时候，RP和EP 互相发送TS1、TS2序列 ，来确定 Different types of ordered sets are Training Sequence, Electrical Idle Sequences, Lane Polarity Inversion, Fast Training Sequence, Start of Data Stream Ordered Set. As mentioned in the previous article, there are the following types of Ordered Sets: TS1 and TS2 Ordered Set (TS1OS/TS2OS), Electrical Idle Ordered Set (EIOS), The ordered sets TS0, TS1, and TS2 have also been redefined to ensure robust communication during the initial equalization phases. u9x1g, gbyd, j6n3o, jmrn, guuf7, m4qvxu, bevfwy, 5d8wh, d96n, etroa,
