求助复用问题：
Reset 定义如下
    set_dft_signal -view existing_dft -type Reset      -port [get_port RSTN_PP ] -active_state 0  -test_mode all_dft

如果定义
    set_dft_signal -view spec -type pll_reset  -port [get_ports RSTN_PP]  -active_state 1 -test_mode all
    插完dft以后报
Error: Line 524 (/tmp/__dft_drc.spf.SPIDERV5.outs.914), illegal context (Clock pin "RSTN_PP" can only be constrained to its off state). (V8-1)
Error: Line 541 (/tmp/__dft_drc.spf.SPIDERV5.outs.914), illegal context (Clock pin "RSTN_PP" can only be constrained to its off state). (V8-2)
Error: Line 558 (/tmp/__dft_drc.spf.SPIDERV5.outs.914), illegal context (Clock pin "RSTN_PP" can only be constrained to its off state). (V8-3)
Error: Line 575 (/tmp/__dft_drc.spf.SPIDERV5.outs.914), illegal context (Clock pin "RSTN_PP" can only be constrained to its off state). (V8-4)

  如果定义
    set_dft_signal -view spec -type pll_reset  -port [get_ports RSTN_PP]  -active_state 0 -test_mode all
多生成了一个pll_reset pin

    set_dft_signal -view spec -type pll_reset  -port [get_ports RSTN_PP] -hookup_pin U_SPIDER_IO/HANDINST_RSTN_IN/X  -active_state 1 -test_mode all


    set_dft_signal -view existing_dft -type Reset      -port [get_port RSTN_PP ] -hookup_pin U_SPIDER_IO/HANDINST_RSTN_IN/X -active_state 0  -test_mode all_dft


两个都加hookup_pin，或者分别加都不行，错误一样，麻烦帮忙看看，谢谢
