在瞬態(tài)分析中的End time, Time Step和Monitor Progress是根據(jù)哪些已知條件設(shè)置的？含義分別是什么？ 我想知道SG1525A這個(gè)芯片的用法，因此想看看該芯片的周圍元件參數(shù)的改變對(duì)SG1525A輸出的影響，但是仿真中出現(xiàn)了錯(cuò)誤，不知道是什么原因，
仿真文件結(jié)果如下：
> dc
The no_ramping algorithm failed. Trying the dyn_ramping algorithm.
Succeeded with the dyn_ramping algorithm.
