设置引脚的脚本：

set pins [dbget top.hInst.hInstTerms.defname] ; # 获取所有引脚
set total_num [llength $pins]
set mid_point [expr $total_num / 2]

set pins_part1 [lrange $pins 0 [expr $mid_point - 1]] ; # 前一半
set pins_part2 [lrange $pins $mid_point end]          ; # 后一半

# ==============================================================================
# 2. 清空并解锁
# ==============================================================================
dbSet [dbGet top.terms].isFixed 0

editPin -pin $pins_part1 -layer M4 -side Left -spreadType CENTER -spacing 0.20 -pinWidth 0.1 -pinDepth 0.2 -snap TRACK
editPin -pin $pins_part2 -layer M6 -side Left -spreadType CENTER -spacing 0.20 -pinWidth 0.1 -pinDepth 0.2 -snap TRACK

设置endcap:

set vars(endcap_left)   "BOUNDARY_LEFTBWP30P140"
set vars(endcap_right)   "BOUNDARY_RIGHTBWP30P140"

set vars(endcap_top)   "BOUNDARY_LEFTBWP30P140 FILL2BWP30P140"
set vars(endcap_bottom)   "BOUNDARY_LEFTBWP30P140 FILL2BWP30P140"

setEndCapMode -reset

setEndCapMode -leftEdge $endcap_left -rightEdge $endcap_right -topEdge $endcap_top -bottomEdge $endcap_bottom -prefix ENDCAP

设置welltap

1 2	set vars(welltap) "TAPCELLBWP30P140" addWellTap -cell $vars(welltap) -cellInterval 60 -prefix WELLTAP
