The following Verilog clock generator module has three parameters to tweak the three different properties as discussed above. The module has an inputenablethat allows the clock to be disabled and enabled as req

13. Using a while loop, design a clock generator. Initial value of clock is 0. Time period for the clock is 10. my answer: 14. Using the for loop, initialize locations 0 to 1023 of a 4-bit register array cache_var to 0. ...
My test platform is an Ubuntu system. I don't normally test the core generator on Windows platforms. Others have used it on Windows platforms quite successfully. There are two problems they have encountered when doing so: I use amkdir(dirname, chmod)function in the core generator to make a...
ICG(Initial Clock Generator)是一种用于Verilog编程语言中的时钟生成器。在Verilog中,我们可以使用ICG来生成初始时钟信号。下面我将从多个角度来介绍ICG的写法。 首先,在Verilog中,我们可以使用always块来实现ICG。我们可以使用always @ (posedge clk)块来检测时钟信号的上升沿,并在上升沿时生成新的时钟信号。示例代码...
