方案二: 采用之前专栏里提到的Verilog-A波形发生器 将波形数据设置为0-1023的遍历 每来一个时钟上升沿,数字变化一次,实现从0-1023的循环 使用方法可以见我的视频,此处不再赘述。 参考代码如下: // This file is generated by the VA_GEN .`include "constants.vams"`include "disciplines.vams"module DAC_STI...
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...
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. ...

The Many approaches have been proposed to reduce EMI, such as shielding box, skew-rate control, and spread spectrum clock generator (SSCG). However, the SSCG has lower hardware cost as compared with other approaches .The proposed technique, a novel portable and all-digital spread spectrum clock...
