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
