TINA/Spice: TINA "Float point" report of 2 cascaded capacitors

Other Parts Discussed in Thread: TINA-TI

Tool/software: TINA-TI or Spice Models

hi,

  there might be a bug in my TINA (v. 9.3.150.328 SF-TI Simplified-Chinese). When two or more capacitors are cascaded, the DRC will fail, reporting "pin 1 of capacitor is float, and the point is not connected to ground", and inconsquence I cann't do DC voltage analysis or AC analysis.

  would you mind have a look at this problem? thank you!
