这个是仿真软件的问题，有时是因为电子线路太复杂导致的仿真计算无法收敛。可以把仿真的精度要求改大点：在“系统”菜单下的“设置模拟仿真”选项中，有时能解决，但不一定能解决所有的问题。
to the Controls panel and select Timestep Options. Change the Minimum Time Step to a very small number, or zero. Zero Minimum Time Step means that the minimum time step size is calculated automatically by the code. The variables affecting the time step are the smallest cell size, gap size...
“timestep is too small"不是~是~时间步太短了~就是说你设计的时间还不够电路的采样和分析的最小时间呢~不太明白~不过~发光二极管是不能直接接电源的吧~怎么也的要个限流电阻什么的~
As I understand it, time step needs to be a factor of the FFT size. There is a lot I have yet to figure out between settling time ( pretty obvious) number of samples, FFT size and minimum step. Vary these parameters and yo can get the same circuit with .0001% distortion, or 1%....
The step size recovers more quickly after it slows down to process the event that occurs before t = 1.02 seconds. This event is less likely to require small step sizes to achieve accurate results. To see different types of slow solver recoveries, zoom to the region within the red box at ...
Change colors or size of elements. When you’re done, clickPublish. Now, with the how-to out of the way, here are the pages you should consider creating: About– I’ve mentioned this a couple of times now since it’s really an important one. Your About page is where you get to te...
Despite its small size, a favicon is a great tool for helping users locate your website in those moments when one too many tabs are open. It will also contribute to your website’s branding by presenting your logo in an extra location, and its sharp appearance adds a measure of professio...
Passage of a soliton through one cell of the link is described by an analytically derived map. Numerical iterations of the map reveal that, at values of the system's stepsize (cell's size) L comparable to the pulse's dispersion length, SSM supports stable pulses which almost exactly ...
Grow medium is very airy and drains quickly Plant feels very light for its size (this means there’s not much water in the grow medium) Learn how to spot and treat under-watering (not as common, but it happens!) Root Rot Roots can get mushy and “rot” in a grow medium that stays...
Example of a 4’x4′ grow tent (this size can easily yield a pound of weed).Poor Grow Lighting Choices (Avoid these!) These are examples of grow lights I’ve seen cannabis growers use, but generally should be avoided. Especially since LED grow lights are a thing!
