我的IP核都有Verilog和VHDL。当我在ISE中使用它时,它没关系。但是,当我把它放在VIVADO 2015.2时,它不起作用,错误信息是这样的:我猜可能在VIVADO中有一些我想念的设置。你能给我一些帮助吗?谢谢,卢myip_cpci_slite_v2_0_project.rar 19 KB以上来自于谷歌翻译以下为原文I have an IP core both have Verilog and VHDL. And when I use it in ISE, it's OK.But when i put it in VIVADO 2015.2 it dosen't work and the error message is like this: I guess that maybe there are some settings I miss in VIVADO. Can you give me some help? Thanks,Lewmyip_cpci_slite_v2_0_project.rar 19 KB

等效电路法又称为低频小信号模型,其具体为:在低频小信号作用下的放大电路中,将放大电路中的基本元件看成一个线性双口网络,利用该网络的h参数来表示放大电路的输入与输出特性便可得到一个等效线性电路,所以也称为h参数等效模型。如何使用万能的三极管等效模型分析各种参数?

你好,我的项目很简单,但同时也很安静(至少对我来说)。我使用的是PIC18F14K22。在PORTB上是一个连接的电阻阵列(DAC类型)。现在在It2上有一个信号连接。我想做的是当INT2上的中断(负边)发生时,PORTB首先遵循一系列步骤,然后尽可能快地遵循LUT(16个步骤)给出的另一系列步骤。端口应该使用这个LUT重复这个序列,直到下一个中断到来,此时相同的步骤将重复,并且端口应该从LUT的第一个元素开始。第一个问题与执行速度有关。为了使用DO-while循环读取PORTB上的数组,每次迭代需要16个循环。理想情况下,我会像在ISR内部那样使用单个命令,但我不知道下一个中断何时到来。第二个问题与ISR的返回有关,所以我可以执行中断发生时没有完成的命令,而不是从头开始。有什么想法吗?

大家好,我正在研究一个简单的电路与PIC12LF1501应该被激活的开关,保持自己的动力通过一个PMOS + NMOS对(PMOS器件绕过电源开关,NMOS驱动PMOS),并关闭自己关闭NIC晶体管通过PIC的RA5,这是主动驱动低。现在的问题是,当电源以这种方式关闭,端口RA5切换到H输出,一旦电源电压下降到约1伏-这就足以再次切换电源。这种情况总是发生,不管我如何配置RA5。我可能需要通过分频网络来驱动NMOS,将栅极电压降低到低于VTH @ 1伏特电源电压,但我想知道是否还有另一种解决方案(如果其他人遇到了同样的问题)。NMOS器件具有相当宽的VTH范围,在0.6到1.5伏特之间,这是复杂的,这只会带来3伏电源电压的问题。也许我最好在这里切换到一个NPN双极晶体管…谢谢你对这件事的任何想法! 以上来自于百度翻译 以下为原文 Hi all,I'm working on a simple circuit with a PIC12LF1501 that is supposed to be activated with a switch, keeping itself powered up via a PMOS+NMOS pair (the PMOS device bypassing the supply switch, NMOS to drive the PMOS), and switch itself off by turning off the NMOS transistor through the PIC's RA5, which is actively driven low. The problem now is that when the power is switched off in this manner, port RA5 switches to a H output as soon as the supply voltage drops to approximately 1 volt -- and this is enough to switch the power back on again. This always happens, regardless how I configure RA5. I probably need to drive the NMOS via a divider network to lower the gate voltage to below Vth @ 1 volt supply voltage, but I wondered if there is another solution to this (and if other people experienced the same problem). It is also complicating that the NMOS device has a rather wide Vth range, between 0.6 and 1.5 volts -- which presents a bit of a problem with only 3 volts supply voltage. Perhaps I'd better switch to an NPN bipolar transistor here ... Thanks in advance for any thoughts on this matter!
