multisim10仿真错误提示 Error:Error:Connecting 'Bidirectional to Power'; [U10 pin COM,Circuit1] to [VCC pin VCC,Circuit1]很多个VCC的错误,如何解决呢? Multisim10仿真时提示错误 求知道,用桥式整流电源就出错,直接接+12就可以运行,求解哪里错了啊,该怎么改正? Multisi数字电路仿真错误提示 multisim10.0.1仿真软件中的电阻怎样竖起来? FLUKE54Ⅱ温度表出现CAL Err错误, protues仿真ARM时提示错误：Simulation is not running in real time due to excessive CPU load 这是我用multisim10软件仿真的电路,为什么数码管没示数,又或者显示到四就出问题了呢? 小功率放大器lm386用什么替代,用multisim10仿真,没有这个,用什么替代?具体怎么用, multisim10中如何加入v= -0.1sin200πt 这样的带有负号的信号源仿真 VB Err.Number=8005和VB Err.Number=8002分别指的什么错误哦 simulink仿真中的问题我在用MATLAB中的SIMULINK做仿真时出现以下错误提示,Trouble solving algebraic loop containing 'chap5_1sim/TmpHiddenBuffer_Feeding_S-Function_AtInput1' at time 3400. Stopping simulation. There may be a singula foxmail提示错误信息:-ERR Internal error occurred.Refer to server log for more information 初学matlab电路仿真出现错误,求解错误提示The diagram must contain a powergui block. The block must be named powergui and should be located at the top-level of your diagram for optimal performance. multisim10.0 波特图示仪 高通滤波器电路仿真,为什么没有显示全呢（如图）?这个应该怎么调整? proteus仿真错误仿真的时候提示如图提示 cannot open ’c＼user＼huazi＼AppData＼local＼temp＼LISA0089．sdf’,请问怎么解决啊,确定不是问题,做的东西有问题,因为把别人正确的东西拿过来也出相同的错 err psw protues 仿真时 提示 no model specified for u2 用simulink里的带通滤波器仿真出现的问题,总提示如下错误,可是不知道错误改怎么改,错误的提示：The sample time of the input signal and the sample time specified in the dialog box must be the same,The sample time of th
