Sourcing proc tcl 导致错误 Options -guard_band or -target_utilization is not allowed for gas-station Voltage Area. (NDMUI-415)

Question

在 ICC2_shell 中获取 tcl 脚本时

`proc vol_area_creation {pd_name blockage_name gb_region} {
    set bbox [get_attribute [get_placement_blockage $blockage_name] bbox]
    set llxn [expr [lindex $bbox {0 0}] + $gb_region]
    set llyn [expr [lindex $bbox {0 1}] + $gb_region]
    set urxn [expr [lindex $bbox {1 0}] - $gb_region]   
    set uryn [expr [lindex $bbox {1 1}] - $gb_region]
    set va_bbox [list [list $llxn $llyn] [list $urxn $uryn]]
    set gb_region   [list [list $gb_region $gb_region]]
    create_voltage_area -power_domains $pd_name -region $va_bbox -guard_band $gb_region
    remove_placement_blockage $blockage_name

}`

我收到一个错误：

Options -guard_band or -target_utilization is not allowed for gas-station Voltage Area. (NDMUI-415) Error: problem in create_voltage_area Use error_info for more info. (CMD-013)

这实际上意味着什么，因为我没有得到错误的任何描述。

我试着先找到剧本然后 给出过程名称

vol_area_creation PD_RISC_CORE pb_1 5.016

什么是加油站电压区？
