【已解决】如下铺出的pg strap，为什么只能铺3条？本意是铺4条。

脚本如下：

create_pg_wire_pattern pattern_wire_based_on_track -layer @l -direction @d -width @w -spacing @s -pitch @p \
                                                   -parameters {l d w s p} ;# -trim true -track_alignment track
create_pg_composite_pattern pattern_pll_area -nets  {PLL_VSS PLL_VDDPOST PLL_VDDHV PLL_VDDREF} \
        -add_patterns {{{pattern: pattern_wire_based_on_track} \
                      {nets: {PLL_VSS PLL_VDDPOST PLL_VDDHV PLL_VDDREF}} \
                      {parameters: {M7 horizontal 8 2.4 50 }}  }}
set_pg_strategy pg_strategy_pll_area -pattern {{name:pattern_pll_area} {nets: {PLL_VSS PLL_VDDPOST PLL_VDDHV PLL_VDDREF}} } \
                                     -polygon {{1194.6200 3400}  {1458.4000 3447.5700}}
compile_pg -strategies { pg_strategy_pll_area} -ignore_via_drc -show_phantom


执行结果log：
icc2_shell> compile_pg -strategies { pg_strategy_pll_area} -ignore_via_drc -show_phantom

交换网络次序，总是第一个网络没有画上。
什么原因？

每一条stripe线宽、间距都要指定。脚本如下：
create_pg_wire_pattern pattern_wire_pll -layer M7 -direction horizontal \
                                        -width {8 8 8 8} -spacing {2.4 2.4 2.4} -pitch 42
set_pg_strategy pg_strategy_pll_area -pattern {{name:pattern_wire_pll} {nets: {PLL_VSS PLL_VDDPOST PLL_VDDHV PLL_VDDREF}} } \
                                     -polygon {{1194.62 34}  {1458.40 3450}}
compile_pg -strategies { pg_strategy_pll_area} -ignore_via_drc -show_phantom ;#-ignore_drc
