进入testbench_verilog文件夹 可以看到如下文件 进入tri_speed_ip 其中tri_speed_ip_tb.v为仿真文件,下面开始仿真 打开ModelSim,切换文件路径到该文件夹下 执行如下命令开始仿真 等待仿真完成,ModelSim打印如下消息: 波形如下: 至此,Tri speed ethernet IP core创建生成并执行官方仿真完成,这些步骤在官方文档中也有介绍:...
Ensure your router and plan support 100Mbps:Connect to your Wi-Fi network and run a speed test viaFast. If the speed is less than 100Mbps, contact your service provider and double-check your internet plan. You can also look up your router online to see if it supports these speeds. Try...
有与PHY MDIO/MDC相连接的信号,以及速度配置和状态指示信号。 下分析波形,当testbench中的sim_start信号拉高后,仿真开始,状态从零开始变化,如下: 查看testbench源文件tri_speed_ip_tb.v中的状态信息 可以看到,仿真开始时,是配置各种寄存器,然后开始向fifo中写数据,之后ip核将数据发送给MII/GMII 发送数据端口,然后...
对Duplex Mode的修改配置也需要复位端口才能生效。 Collision Test:冲突信号(COL)测试开关。在需要对COL信号进行测试时,可以通过Bit7置1,这时PHY将输出一个COL脉冲以供测试。实际测试操作中也可以将端口配置为半双工状态,通过发帧冲突来测试COL信号,因此该配置实用价值不大。 Unidirectional enable:如果PHY通过比特1.7报...

1. Have you changed the speed/duplex on the switch interface? Y/N? 2. What is the switch interface currently set at? 3. Did you change the router interface to auto/auto or was it already that way? 4. If you did change the router config for that interface, did you bounce the inter...
Speed test over Ethernet = 350mbps Speed test over WiFi = 140mbps Even though it shows higher speeds over Ethernet, loading websites is still a lot slower over ethernet than WiFi. Not sure how that‘s possible, but it‘s what the tests say. Reply User profile for user: Grant Bennet-...
The class interface speed to the DDR controller is 400 MHz. At this rate, the external MCK signal to the 32-bit DDR devices on the ADS is 200 MHz (providing an effective bandwidth of 400 MHz at 32 bits). 5.1.6.1 Programming Model The general programming model for this test is very ...
