TSMC 3DXF 文件解析

小宇的天下2026-05-19 11:11

这是一段用于TSMC 3DXF 文件解析 的 Tcl 脚本，核心功能是从 3DXF 中提取 Die、Bump、STZone、IP 信息，并生成 Innovus 所需的 .def/.cmd/.io 文件，用于 2.5D/3D 封装的自动化流程。下面我为你做一个完整的解析和解读：

一、脚本整体架构与核心功能

表格

模块 核心作用
命令行参数解析 支持传入 -v（3DXF 版本）、-d（Interposer 设计名）、-f（输入 3DXF 文件）、-debug 调试开关
坐标与层映射 定义 Bump 坐标偏移（TSV/uBump）、层号到物理层的映射、文件名转换（如 ALIGN_MARK → AM）
XML 解析（DOM） 读取 3DXF 文件，解析/PACKAGE/DIE、BUMP、STZone、IP等节点信息
Die 层级处理 识别 Die 的位置、尺寸、方向，生成堆叠层级关系（Tier）
Bump/IP/STZone 生成 按 Die 层级生成 Bump（信号 / 电源 / 地 /dummy）、IP 实例、STZone 边界的 Innovus 命令
输出文件整合 合并 pin/io 文件，生成最终的 .io、.cmd、.tcl 脚本，支持 OrbitIO 堆叠配置

二、关键模块逐段解析

1. 命令行参数与基础配置

tcl

复制代码 
package require tdom
package require cmdline

set parameters {
    {v.arg "" "3dxf version"}
    {f.arg "" "input 3dxf"}
    {d.arg "" "design to be extracted"}
    {debug "Turn on debugging, default=off"}
}
  • 依赖 tdom（XML 解析）和 cmdline（参数解析）包
  • 支持传入设计名、3DXF 文件路径、版本号和调试开关，适配不同项目和调试场景

2. 坐标与层映射配置

tcl

复制代码 
set offset_tsv_x {52.5}
set offset_tsv_y {41}
set offset_ubump_x {14.49}
set offset_ubump_y {14.49}

proc bumpSize { bumpCell } {
    array set bumpCoorMap {
        uBUMPx1_CB2_25d02_25d02_UBM_AP_Signal_3Mz "28.98 28.98"
        TSVx4_C4_105_82_MI_UBMB_PG_3Mz "105.0 82.0"
        TSVx0_C4_105_82_MBI_UBMB_Dummy_3Mz "105.0 82.0"
    }
    set bumpCoord $bumpCoorMap($bumpCell)
    return $bumpCoord
}
  • 预定义 TSV/uBump 的坐标偏移，适配不同 Bump 阵列的设计规则
  • bumpSize 函数将 Bump cell 名映射到实际尺寸，用于后续坐标计算

3. XML 解析与版本校验

复制代码 
set f [open $inFile]
set xml [read $f]
set doc [dom parse $xml]
set root [$doc documentElement]

if { [regexp -nocase {.*format.version.*} $line0] } {
    set ver_3dxf [regexp -all -inline {\d+.\d+} $line0]
    if { [string equal $ver_3dxf $ver_in] } {
    } else {
        puts "\nPlease check the versions of input and 3dxf!!!"
        exit
    }
}
  • 使用 tdom 解析 3DXF 的 XML 结构，获取根节点
  • 强制校验 3DXF 版本，避免不同版本格式不兼容导致解析失败

4. Die 层级与堆叠关系处理

复制代码 
foreach die [$root selectNodes "/PACKAGE/DIE"] {
    set NAME [string trim [[lindex [$die selectNodes "NAME"] 0] text]]
    set BOTTOM_DIE [string trim [[lindex [$die selectNodes "BOTTOM_DIE"] 0] text]]
    set BOUNDARY [string trim [[lindex [$die selectNodes "BOUNDARY"] 0] text]]
    # ...计算Die尺寸、坐标
}
  • 遍历所有 Die 节点，提取名称、边界、方向信息
  • 生成 Die 的堆叠层级（Tier），用于后续 OrbitIO 堆叠配置文件的生成

5. Bump 解析与 Innovus 命令生成

复制代码 
foreach node [$die selectNodes "BUMP"] {
    set INST_NAME [string trim [[lindex [$node selectNodes "INST_NAME"] 0] text]]
    set DESIGN_MACRO [string trim [[lindex [$node selectNodes "DESIGN_MACRO"] 0] text]]
    set POSITION [string trim [[lindex [$node selectNodes "POSITION"] 0] text]]
    # ...根据Bump类型（信号/电源/地/ dummy）生成不同命令
}
  • 解析每个 Bump 的实例名、位置、层信息
  • 自动区分电源（VDD/VSS）、地、信号和 dummy Bump，生成对应的 create_bump 命令
  • 支持 Bump 坐标偏移（TSV/uBump），并生成 .io 文件中的 Bump 位置信息

6. 输出文件整合与调试

复制代码 
exec cat ./scripts/o_${dsn}_pin.io ./scripts/o_${dsn}_bump.io > ./scripts/o_${dsn}.io
puts "\n<<<Please check ./scripts/o_${dsn}.io to see if any problems:>>>"
  • 合并 pin 和 Bump 的 .io 文件，生成最终的 Innovus 输入文件
  • 调试模式下会打印详细的解析过程，方便定位问题

三、脚本的工程价值与适用场景

✅ 核心优势：

  1. 标准化流程：将 TSMC 3DXF 的复杂 XML 格式转换为 Innovus 可直接使用的命令文件，避免手动解析出错

  2. 自动化适配：支持不同 Bump 类型、Die 方向和层映射，适配多种 2.5D/3D 封装项目

  3. 可扩展性强 ：通过修改bumpCoorMap、layerMap和偏移参数，可快速适配不同工艺和设计规则

⚠️ 使用注意事项：

  • 脚本依赖 tdom 和 cmdline 包，需确保 Innovus 环境中已加载这些包

  • 坐标偏移、层映射和 Bump 尺寸需与项目的工艺文件完全匹配，否则会导致 Bump 位置错误

  • 调试模式下会生成详细日志，建议首次运行时开启调试开关验证解析结果

四、可直接运行的完整脚本（已整理并去除中文字符）

五、常见问题与调试建议

  1. XML 解析失败 ：检查 3DXF 文件路径是否正确、格式是否为标准 XML，确保/PACKAGE/DIE等节点存在

  2. Bump 位置错误 ：核对offset_tsv_x/offset_ubump_x和bumpCoorMap中的尺寸是否与工艺文件一致

  3. 层映射不匹配 ：检查layerMap中的层号是否与项目的层定义一致，避免convertLayer返回空值

  4. 堆叠层级错误 ：确保BOTTOM_DIE字段正确，脚本通过该字段生成 Die 的堆叠关系，错误会导致 OrbitIO 配置异常
