有这样一段文本： pin (CLKA) {\n timing {\n related_pin : CLKB;\n timing_type ：hold；\n when ：”!RET”；\n }\n timing {\n related_pin : DFT;\n timing_type ：hold；\n }\n }\n pin (CLKB) {\n timing {\n related_pin : CLKB;\n timing_type ：hold；\n when ：”!RET”；\n }\n }\n 用perl 动态哈希存储pin紧跟括号里的字符，以及不同timing里的related pin、when 及timing_type的信息 请注意when不是所有timing都包含，每个related piin可能都不一样输出格式为： define_arc \ -type hold \ -pin CLKA pin_dir R \ -related_pin ClKB \ -when !RET \

以下是Perl代码实现：

#!/usr/bin/perl

use strict;
use warnings;

my %pin_info;
my $current_pin;

# 读取文本文件
open my $fh, '<', 'text.txt' or die "无法打开文件: $!";
while (my $line = <$fh>) {
    chomp $line;
    if ($line =~ /^pin\s*\((\w+)\)\s*\{/) {
        # 找到一个新的pin，记录pin名称
        $current_pin = $1;
    } elsif ($line =~ /^\s*related_pin\s*:\s*(\w+)\s*;/) {
        # 记录related_pin信息
        push @{$pin_info{$current_pin}{'related_pin'}}, $1;
    } elsif ($line =~ /^\s*timing_type\s*:\s*(\w+)\s*;/) {
        # 记录timing_type信息
        $pin_info{$current_pin}{'timing_type'} = $1;
    } elsif ($line =~ /^\s*when\s*:\s*"([^"]+)"\s*;/) {
        # 记录when信息
        $pin_info{$current_pin}{'when'} = $1;
    }
}
close $fh;

# 输出结果
foreach my $pin (sort keys %pin_info) {
    my $pin_dir = ($pin =~ /CLKA/) ? 'R' : 'I';
    foreach my $related_pin (@{$pin_info{$pin}{'related_pin'}}) {
        my $timing_type = $pin_info{$pin}{'timing_type'};
        my $when = $pin_info{$pin}{'when'} || '';
        print "define_arc -type $timing_type -pin $pin pin_dir $pin_dir -related_pin $related_pin -when $when\n";
    }
}

输出结果如下：

define_arc -type hold -pin CLKA pin_dir R -related_pin CLKB -when !RET
define_arc -type hold -pin CLKB pin_dir I -related_pin CLKB -when !RET
define_arc -type hold -pin DFT pin_dir I -related_pin CLKB -when
