wrusedw:表示已经写了多少数据 rdusedw: 表示还可以读多少数据 在FPGA的设计中常用这两个信号控制wrreq以及rdreq。 Quartus II中FIFO配置界面 对配置的fifo进行例化,wrclk连接在pclk(OC5640数据输出时钟),rdclk连接在GMII_GTXC,即将在pclk和GMII_GTXC这两个时钟域进行数据交换,也就是图像采集模块(Camera_ETH_Format...
在win10下拖曳器件会发生残影的现象,而且无法修改连线。虽然有自动连线功能但感觉线连的挺乱的。但好在它有quartus没有的CD系列芯片如我们做实验用过的CD4015开关按钮开始仿真,调用逻辑分析仪查看波形,与multisim有点类似但连线还是quartus整齐,以及命名线的端口的方式......
jk触发器设计d触发器,根据原理图实现模8加1计数器,来源于西电慕课貌似这个软件只有5.0和5.12两个版本。在win10下拖曳器件会发生残影的现象,而且无法修改连线。虽然有自动连线功能但感觉线连的挺乱的。但好在它有quartus没有的CD系列芯片如我们做实验用过的CD4015开关按钮开始仿真,调用逻辑分析仪查看波形,与multisim...
I have been coding a simple FSM and datapath in Quartus II 11.1, When I examine the post-fit netlist in the Technology Viewer, I notice that certain registers/flip flops have the "normal" setup of D data in, CLK, CLRN, but then there are other flip flops where there are additional ...
本次课程设计需要利用 Quartus II 软件进行仿真和综合,并需要 使用 DE10-Lite 开发板进行验证。在设计过程中,需要注意电路自检 功能以及实际调试时电路的稳定性和可靠性。 二、设计基础电路 1. 组合逻辑电路 1.1 电路设计目标 将任意两个 4 位二进制数进行加法运算,并将结果以 4 位二进制码 输出。 数字集成...
it will be prone to timing issues, which you are probably seeing in the waveform (as the quartus simulator only simulates gate level designs). FPGAs are designed for clocked flip-flops. Have you got a testbench for this code? have you tried modelsim instead? Translate 0 Kudos Copy ...
