DFT Compiler會自動插入test_se, test_si, test_so ...

在script已經宣告 scan enable, scan input, scan output 為別的port
  set_DFT_signal -view existing_dft -type ScanEnable      -active_state 1 -port  SPA1  
  set_scan_configuration -chain_count 7 -add_lockup true -clock_mixing mix_clocks  
  set_dft_signal -view spec -type ScanDataIn  -port SPB0
  set_dft_signal -view spec -type ScanDataOut -port SPB1
  set_dft_signal -view spec -type ScanDataIn  -port SPB2
  set_dft_signal -view spec -type ScanDataOut -port SPB3
  set_dft_signal -view spec -type ScanDataIn  -port IO14
  set_dft_signal -view spec -type ScanDataOut -port IO15
  set_dft_signal -view spec -type ScanDataIn  -port IO11
  set_dft_signal -view spec -type ScanDataOut -port IO17
  set_dft_signal -view spec -type ScanDataIn  -port IO24
  set_dft_signal -view spec -type ScanDataOut -port IO25
  set_dft_signal -view spec -type ScanDataIn  -port IO26
  set_dft_signal -view spec -type ScanDataOut -port IO27
  set_dft_signal -view spec -type ScanDataIn  -port I2CC
  set_dft_signal -view spec -type ScanDataOut -port IO21
  set_scan_path chain_1 -view spec -scan_data_in SPB0 -scan_data_out SPB1
  set_scan_path chain_2 -view spec -scan_data_in SPB2 -scan_data_out SPB3
  set_scan_path chain_3 -view spec -scan_data_in IO14 -scan_data_out IO15
  set_scan_path chain_4 -view spec -scan_data_in IO11 -scan_data_out IO17
  set_scan_path chain_5 -view spec -scan_data_in IO24 -scan_data_out IO25
  set_scan_path chain_6 -view spec -scan_data_in IO26 -scan_data_out IO27
  set_scan_path chain_7 -view spec -scan_data_in I2CC -scan_data_out IO21
可是最後合成的file,還是會被增加test_si1, test_so1,
        test_si2, test_so2, test_si3, test_so3, test_si4, test_so4, test_si5,
        test_so5, test_si6, test_so6, test_si7, test_so7, test_se這麼多port
請各方能人解答一下

我大概知道問題 這些port在原來的設計都是inout port,並不是單純地 input 或是output
那要怎樣宣告呢?

我还是不懂

你定义的那些端口都是function的端口，用作scan端口时，需要先做pinshare，让scanmode选择这些端口在scan时是input还是output
