xml - 如何绘制由 IAR Embedded Workbench 生成的 xml 调用图？

Question

在 IAR Embedded Workbench (v 8.40.1.21539) 中，我启用了

Project => Options => Linker => Advanced => Enable stack usage analysis

并已将“callgraph.xml”指定为 Call graph output (XML)文件。
IAR 现在生成了一个可爱的(巨大的)xml 文件，其中包含以下形式的条目:

<?xml version="1.0" encoding="UTF-8"?>

<callGraph>
  <version>2</version>
  <modules>
    ...
  </modules>
  <functions>
    ...
    <function>
      <id>771</id>
      <name>papi_ssd1675_iface_reset</name>
      <address>0x3&apos;6db9</address>
      <stack>8</stack>
      <callee>759</callee>
      <callee>1057</callee>
    </function>
    ...
  </functions>
  ...
</callGraph>

现在:什么实用程序(或实用程序)知道如何以图形方式绘制它？

我使用这个python脚本将xml转换为点图，可以转换为svg

import xml.etree.ElementTree as ET
import code


def parseNodes(functionsNode):
    for function in functionsNode:
        name = None
        identifier = None        
        for prop in function:
            if(prop.tag == "id"):
                identifier = prop.text
            if(prop.tag == "name"):
                name = prop.text
        print('f%s [label="%s"]'%(identifier,name))
def parseEdges(functionsNode):
    for function in functionsNode:
        identifier = None
        callees = []        
        for prop in function:
            if(prop.tag == "id"):
                identifier = prop.text
            if(prop.tag == "callee"):
                callees.append("f"+prop.text)
        if len(callees)>0:
            print('f%s -> %s'%(identifier,"->".join(callees)))

def main():
    tree = ET.parse('CallGraphStack_P1.xml')
    root = tree.getroot()
    functionsNode = None;
    for child in root:
        if(child.tag == "functions"):
            functionsNode = child
    parseNodes(functionsNode)
    parseEdges(functionsNode)
    #code.interact(local=locals())




main()
