第一步:打开之前用到的 LTM8065 模拟文件,将负载电流源的最大值设为 {X},具体为:PULSE (0.5 {X} 600u 100u 100u 300u) 第二步:输入 .step 命令:.step param x 1 2.5 0.5 第三步:运行仿真模拟,如下图 (图6) 所示,确认 1~2.5A 每变化 0.5A 的输出电压波动结果。 图6 负载电流最大值...

Step 3: Set the Measurement Parameters A few more small directives are needed. First, the circuit must be in a steady state of the simulation (past startup) in order to make proper measurements. Adjust the t0, or start time for the measurement, and stop time. The start time can...
Once you’ve mastered the basics of LTspice, you’re ready to go deeper with the resources below. Learn how to use LTspice for more complex simulations by manipulating parameters, pulling in external data, adjusting for noise, and more. ...
I've written quite a bit of fully parallel code, running on dedicated threads to take advantage of multiple cores, for the Win32 environment so I'm painfully familiar with how people can do it incorrectly. I accept that LTSpice isn't fully optimized to take advantage of all the cores in...
, the spice core will perform multiple individual simulations, each one with a different set of parameters according to the stepping scheme. the .step directive can't step parameters during a running transient simulation. to step at different time points within a single transient simulation, use ...
I defined the IGBT parameters as variables and changed this by a tool to simulate a fractional DOE table. The tool will write a netlist and start LTspice in batch mode, but with a single manual start of LTspice with the same IGBT parameters I have the same error; it is independent...
