We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

参见说明 https://support.lumerical.com/hc/en-us/articles/360034918833-Boundary-Conditions-in-CHARGE-Simulation-Object APPLY AC SMALL SIGNAL: This option is valid only during small-signal ac simulations. The value is set to NONE by default. When enabled it applies a small signal AC voltage to the DC bias voltage.
  • all: SSAC voltage will be applied to all bias points.
  • last: SSAC voltage will only be applied to the last bias point.
如果不是仿真小信号分析，不用理会这个设置。
