凌力尔特公司推出 LTspice IV ,这是其免费 SPICE 电路仿真软件所做的一次重大更新。LTspice IV 具有专为提升现有多内核处理器的利用率而设计的多线程求解器。另外,该软件还内置了新型 SPARSE 矩阵求解器,这种求解器采用汇编语言,旨在接近现用 FPU (浮点处理单元) 的理论浮点计算限值。当采用四核处理器时,LTspice IV 可将大中型电路的仿真速度提高 3 倍。
3.8. Current Measurements
Make the circuit diagram window active.(...by a left mouseclick on it....) and move the cursor exactly over thecomponent of which you want to know the current. The cursor changes to a "current sensor" and with a leftmouseclick on the component you will see the trace current displayed in the waveform viewer..
Example:
Current in resistor R1 (Collector resistor of the left transistor, Q2):
