pullup和pulldown并非是verilog的内置原语,仅在仿真或综合过程中起作用,用来设置信号的默认状态 在实际的硬件电路中,用来代表上拉和下拉,就比如在I2C中,SCL和SDA两个信号是open-drain的,在实际使用过程中往往需要接上拉电阻,如下图 接在VCC的两个电阻就是上拉电阻,这个上拉电阻在verilog中就可以用pullup表示 下面...
In reply to dave_59: Hi Dave, Please help me. Can you explain about it? pullup(dp); If I use this method to pullup pin dp. I read the SystemVerilog Document but it is complicated. I can’t understand clearly. And another question: what do you think if I replace command pullup(...
