标题: 如何给pin1 pin2 赋值
我需要写一个能自动列出pin pair长度报表的skill插件，

软件最终具体操作如下，

1.先提供一个pin pair 的表格，如：

I3C_SPD_DDRABCD_CPU0_LVC1_SCL	R725.1	R189.1
I3C_SPD_DDRABCD_CPU0_LVC2_SCL	R189.1	R193.1
I3C_SPD_DDRABCD_CPU0_LVC3_SCL	R193.1	R197.1
I3C_SPD_DDRABCD_CPU0_LVC4_SCL	R197.1	R201.1
I3C_SPD_DDRABCD_CPU0_LVC1_SDA	R724.1	CPU1_DIMM_A1.5
I3C_SPD_DDRABCD_CPU0_LVC2_SDA	CPU1_DIMM_A1.5	CPU1_DIMM_B1.5
I3C_SPD_DDRABCD_CPU0_LVC3_SDA	CPU1_DIMM_B1.5	CPU1_DIMM_C1.5
I3C_SPD_DDRABCD_CPU0_LVC4_SDA	CPU1_DIMM_C1.5	CPU1_DIMM_D1.5

2. 通过skill软件跑出如下含pin pair 长度的报表

I3C_SPD_DDRABCD_CPU0_LVC1_SCL	R725.1	R189.1	2987.12
I3C_SPD_DDRABCD_CPU0_LVC2_SCL	R189.1	R193.1	402.83
I3C_SPD_DDRABCD_CPU0_LVC3_SCL	R193.1	R197.1	428.85
I3C_SPD_DDRABCD_CPU0_LVC4_SCL	R197.1	R201.1	318.66
I3C_SPD_DDRABCD_CPU0_LVC1_SDA	R724.1	CPU1_DIMM_A1.5	3113.70
I3C_SPD_DDRABCD_CPU0_LVC2_SDA	CPU1_DIMM_A1.5	CPU1_DIMM_B1.5	515.15
I3C_SPD_DDRABCD_CPU0_LVC3_SDA	CPU1_DIMM_B1.5	CPU1_DIMM_C1.5	553.05
I3C_SPD_DDRABCD_CPU0_LVC4_SDA	CPU1_DIMM_C1.5	CPU1_DIMM_D1.5	368.80

目前我查出使用函数 axlDBPinPairLength(Pin1 pin2) 来编写，
axlDBPinPairLength(
o_pin1
o_pin2
)
==> f_etchlength/nil

Description
Calculate the shortest length between 2 pins. Pins must be on the same xnet. The pin can also be a VIA or RAT_T. If the distance is not fully routed, it includes a Manhattan estimate of the unrouted portion.
Includes VIA-Z or PIN_DELAY in its calculation if these options are enabled and if your license permits this capability.

Example
Skill> pin1 = ashOne()
Skill> pin2 = ashOne()
Skill> axlDBPinPairLength(pin1 pin2)
-> 2676.777

但我不知道o_pin1，o_pin2如何赋值。比如，
当netname 为 I3C_SPD_DDRABCD_CPU0_LVC1_SCL时，o_pin1 = R725.1 o_pin2 = R189.1
求大神帮忙
